Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 13-6.
The alternate pin configuration is as follows:
• INT0 – Port D, Bit 1
INT0, External Interrupt Source 0. The PD1 pin can serve as an external interrupt source to the
MCU.
• ICP1 – Port D, Bit 0
ICP1 – Input Capture pin1: The PD0 pin can act as an Input Capture pin for Timer/Counter1.
