GPIO

The CT Board offers on the 4 general purpouse ports the following functions:

• 4 general purpouse I/O ports
  • 32 memory mapped output pins
  • 32 memory mapped input pins
• 2 general purpouse I/O ports, directly connected to MCUs Port A and B
• External interface to SRAM bus.

Each of the 4 GPIO ports contains 8 ouput and 8 input pins. The ports are not as fast as the integrated GPIO ports of the microcontroller.

Please make sure the CT Board is in the correct mode.
Supported mode: 1

The Registers are read / write.

These two ports are directly connected to the GPIO ports A and B on the microcontroller.
All functions of theese GPIO ports are available.

This functionality is independent of the CT Board mode.
Supported modes: Available in all modes.

Only pins 0..11 are connected to P5 / P6! The other 4 pins are used for 5V, 3.3V and GND.
