Target CPU Window

This window displays selected target CPU with its peripherals and pins (possible data directions of single pins are indicated by blue arrows on the CPU package when a bean uses these pins). Several display modes are supported. It is possible to switch the display mode by pushing buttons in the left side menu of the window.

Control Buttons

The meanings of the buttons on the left side are:

Rotates CPU - rotate the CPU 90 degrees to the right.
Show user names on CPU package - switches the pins' and peripherals' default names (from catalog) for user-defined names.
Zoom in - increases the detail level of the view. The whole picture might not fit the viewing area.
Zoom out - decreases the detail level of the view. Processor Expert tries to fit the whole picture to the viewing area.
Show CPU package and peripheral - switches to the CPU package view mode.
Show BGA CPU package - switches to the CPU BGA package view mode.
Show CPU block diagram - switches to the CPU block diagram view mode.
Show CPU peripherals in a list - switches to the CPU peripherals list view mode.

View Modes

CPU package mode - a realistic view of the CPU package with pins and peripherals. Each allocated peripheral contain an icon of the bean that allocates it. For allocated pins also the bean icon with the connection is shown.

Figure 1 - Target CPU - CPU package view mode

CPU BGA package mode - This mode is available only for CPUs with grid-array pins layout. It is similar to the package mode, but the pins hidden by package are shown and the peripherals are hidden.

Figure 2 - Target CPU - BGA CPU package view mode

CPU block diagram mode - a view of the CPU block diagram based on the documentation of the CPU manufacturer. Every part of the CPU is represented by a block. Every block that contains a resources that can be allocated by Processor Expert contains the slots for every resource (e.g. pin or channel). If the resource is allocated, the slot contains the icon of the allocating bean.

Figure 3 - Target CPU - MCU block diagram view mode

CPU peripherals list - a list of all peripherals of the CPU is displayed. If a peripheral is unallocated by Processor Expert, it is displayed as a gray icon. Otherwise, the icon of the bean that allocates the peripheral is displayed. The same mouse commands are available as in the other view-modes, except the operations with pins (pins are not visible in this mode).

Figure 4 - Target CPU - Peripherals List Mode

Pins

The following information about each pin is displayed on the CPU picture:
(all pins are displayed only in the CPU package view mode)

pin name (default or user-defined)
icon of a bean that uses (allocates) the pin
direction of the pin (input, output, or input/output) symbolized by blue arrows, if a bean is connected

Pin names are shortened and written either from left to right or from up to down and are visible only if there is enough space in the diagram.

Some signals and peripherals cannot be used by the user because they are allocated by special devices such as power signals, external or data bus. The special devices are indicated by a special blue icons, for example . The allocation of peripherals by special devices can be influenced by CPU properties.

Hints

Pin hint contains:

number of the pin (on package)
both names (default and user-defined)
owner of the pin (bean that allocates it)
short pin description from CPU database

Bean icon hint contains:

bean name
bean type
bean description

Shared Pins

If a pin is shared by multiple beans, the line connecting the pin to the bean has a red color. See chapter Pin Sharing for details.

Figure 5 - Shared pin connection

On-chip peripherals

The following information about each on-chip peripheral is displayed on the CPU package:

peripheral device name (default or user-defined)
icon of the bean that uses (allocates) the peripheral device

Peripheral device hint contains:

peripheral device name
owner of the pin (bean that allocates it)
short peripheral device description

Hint on icon contains:

bean name
bean type
bean description

If a peripheral is shared by several beans (for example: several beans may use single pins of the same port), the icon is displayed.

Note for peripherals working in several modes:
Some peripherals work in several modes and these peripherals can be represented by a several devices in the CPU databases. For example, the device "TimerX_PPG" and "TimerX_PWM" represents TimerX in PPG and in PWM mode. These devices can be displayed on the CPU package, but they are also represented as a single block in the MCU block diagram.

Mouse Operations For Individual Items

Single click on a bean icon selects the bean in the Project panel.
Double click on a bean icon opens its Bean Inspector and selects the property specifying the peripheral used by the bean.
Double click on a peripheral opens the simple item structure view.
Double click on an icon opens a selection menu with all the beans that use single parts of the peripheral. Selecting one bean opens it in the Bean Inspector.
Right button click on a bean icon opens the Bean pop-up menu. If the Bean Inspector is invoked from this pop-up menu, an appropriate property allocating the used peripheral is selected.
Right button click on an icon opens selection menu with all the beans that use single parts of the peripheral. Selecting one bean opens the Bean pop-up menu.
Right click on the peripheral opens the Peripheral Pop-up menu (see below).

Peripheral/Pin Pop-up Menu

The following commands are available in the pop-up menu:

Show Peripheral Initialization - shows initialization values of all "control, status and data" registers. This option is supported for all devices displayed on a CPU package. See chapter Peripheral Initialization for details.
Show Peripheral Structure - opens the peripheral's structure view - (it is supported for I/O ports, timer's counters, serial ports. This option is also supported for devices working in several modes in the CPU block diagram. A list of represented devices for these modes is displayed.
Show Peripheral Usage - shows which part of the peripheral is used by the application (visible after code generation). This option is supported for I/O ports and pins, timers, A/D converters and A/D channels, CAN, serial ports, watchdog, internal memories (EEPROM and FLASH). See chapter Peripherals Usage for details.
Rename Peripheral - allows you to rename the selected peripheral. It is supported for I/O ports and pins, watchdog and timers (counters, compare and capture registers, free running devices), A/D converters and A/D channels, CAN, serial ports.
Search Related Info In CPU PDF Documentation displays PDF Search window and finds the information about the peripheral in the appropriate CPU documentation. It is also possible to search for any keyword in the CPU documentation based on the original manufacturer's CPU manual. (This item is available on the package and on the CPU block only.) See chapter PDF Search for details.
Add Bean/Template - adds a bean or template for the appropriate peripheral: all available beans and templates suitable for the selected peripheral are listed. The beans and templates in the list are divided by a horizontal line. It is possible to add only beans or templates which are applicable for the peripheral. It means that is possible to add the bean or template only if the peripheral is not already allocated to another bean or beans. The beans/templates that cannot be added to the peripheral are grayed in the pop-up menu as unavailable. This option is supported for all devices displayed on CPU package.
