GPTE
General Purpose Timer Modules (GPTA and GPTB)
The PORTTn data direction register controls the data direction of an input capture pin. External pin
conditions trigger input captures on input capture pins configured as inputs.
To configure a pin for input capture:
PORTTnDDR does not affect the data direction of an output compare pin. The output compare function
overrides the data direction register but does not affect the state of the data direction register.
To configure a pin for output compare:

2. Clear the pin’s DDR bit in PORTTnDDR.
3. Write to GPTCTL2 to select the input edge to detect.
1. Set the pin’s IOS bit in GPTIOS.
2. Write the output compare value to GPTCn.
3. Clear the pin’s DDR bit in PORTTnDDR.
4. Write to the OMn/OLn bits in GPTCTL1 to select the output action.
