Alternate Functions of Port H
Table 12-23. Overriding Signals for Alternate Functions in PG3:PG0
The Port H alternate pin configuration is as follows:
Table 12-24. Port H Pins Alternate Functions
• T4 – Port H, Bit 7
T4, Timer/Counter4 counter source.
• OC2B – Port H, Bit 6
OC2B, Output Compare Match B output: The PH6 pin can serve as an external output for the
Timer/Counter2 Output Compare B. The pin has to be configured as an output (DDH6 set) to
serve this function. The OC2B pin is also the output pin for the PWM mode timer function.
• OC4C – Port H, Bit 5
OC4C, Output Compare Match C output: The PH5 pin can serve as an external output for the
Timer/Counter4 Output Compare C. The pin has to be configured as an output (DDH5 set) to
serve this function. The OC4C pin is also the output pin for the PWM mode timer function.
