Direction methods - These methods concern the direction of the bean (encapsulation of the direction of the allocated physical device).
The direction is expressed as a boolean value:
FALSE = input, TRUE = output.
Value methods - These methods work with the whole width of the bean (with the 8 bits together).
Bit methods - These methods work with a single bit of the bean. The bit is specified as a number from 0 to 7.
The bit value is expressed as a boolean value: FALSE is "0" or "Low", TRUE is "1" or "High".


GetDir - Return selected direction.

ANSIC prototype: bool GetDir(void)

• Return value:bool - FALSE = Input, TRUE = Output


SetDir - Set port direction.

ANSIC prototype: void SetDir(bool Dir)

• Dir:bool - Direction to set - FALSE = Input, TRUE = Output


GetVal - Return the value of the Input/Output bean. If direction is input then reads the input value of the pins and returns it. If direction is output then returns the last written value.

ANSIC prototype: byte GetVal(void)

• Return value:byte - Input value


PutVal - Put the specified value to the Input/Output bean. If direction is input saves the value to a memory or a register, this value will be written to the pins after switching to the output mode - using SetDir(TRUE). If direction is output writes the value to the port.

ANSIC prototype: void PutVal(byte Val)

• Val:byte - Output value


GetBit - Return the value of the specified bit/pin of the Input/Output bean. If direction is input then reads the input value of the pin and returns it. If direction is output then returns the last written value.

ANSIC prototype: bool GetBit(byte Bit)

• Bit:byte - Number of the bit to read (0 to 7)
• Return value:bool - Bit value


PutBit - Put the specified value to the specified bit/pin of the Input/Output bean. If direction is input saves the value to a memory or a register, this value will be written to the pin after switching to the output mode - using SetDir(TRUE). If direction is output writes the value to the pin.

ANSIC prototype: void PutBit(byte Bit,bool Val)

• Bit:byte - Number of the bit (0 to 7)
• Val:bool - New value of the bit (FALSE or TRUE) FALSE = "0" or "Low", TRUE = "1" or "High"


SetBit - Set (set to one) the specified bit of the Input/Output bean. It is the same as PutBit(Bit,TRUE).

ANSIC prototype: void SetBit(byte Bit)

• Bit:byte - Number of the bit to set (0 to 7)


ClrBit - Clear (set to zero) the specified bit of the Input/Output bean. It is the same as PutBit(Bit,FALSE).

ANSIC prototype: void ClrBit(byte Bit)

• Bit:byte - Number of the bit to clear (0 to 7)


NegBit - Negate (invert) the specified bit of the Input/Output bean. It is the same as PutBit(Bit,!GetBit(Bit)).

ANSIC prototype: void NegBit(byte Bit)

• Bit:byte - Number of the bit to invert (0 to 7)

Note: Some methods can be implemented as macros.
