* Question
| Which registers are controlled by each pin that is a GPIo function? |
* Answer
| Each pin that functions as a GPIo function is controlled by four registers, IoxDIR for control direction, IoxSET and IoxCLR for controlling output level status, and IoxPIN for reflecting pin level status.These four registers form a group, and a group of registers controls one port (P0, P1, P2, or P3). |
