Port data reg addr - Port data register address in external address space.
Port direction reg addr - Port direction register address in external address space.
Bit number (0..7) - Pin number in external port (from 0 to 7).
Direction - Direction of the bean: input, output, input/output (the direction of the pin can be switched in run time - see SetDir method).
Initialization - Initial settings (after power-on or reset).
• Init. direction - Initial direction - input or output (available only if Direction = input/output).
• Init. value - Initial output value = 0 or 1 (available only if Direction = output or input/output).
Safe mode - Hold output value (I/O bean holds output value, even if set as input).
Optimization for - Whether the driver is optimized for speed or for code size.
