Alternate Functions of Port D
2466J–AVR–10/04
Table 30. Overriding Signals for Alternate Functions in PC3..PC0
Note:
The Port D pins with alternate functions are shown in Table 31.
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 output 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.

pins PC0 and PC1. This is not shown in the figure. In addition, spike filters are con-
nected between the AIO outputs shown in the port figure and the digital logic of the
TWI module.
