Alternate Functions of

2503Q–AVR–02/11
Table 30. Overriding Signals for Alternate Functions in PC3..PC0
Note:
The Port D pins with alternate functions are shown in
Table 31. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• OC2 – Port D, Bit 7
OC2, Timer/Counter2 Output Compare Match output: The PD7 pin can serve as an external out-
put for the Timer/Counter2 Output Compare. The pin has to be configured as an output (DDD7
set (one)) to serve this function. The OC2 pin is also the output pin for the PWM mode timer
function.
• ICP1 – Port D, Bit 6
ICP1 – Input Capture Pin: The PD6 pin can act as an Input Capture pin for Timer/Counter1.
