Alternate Functions of Port D
2573G–AVR–07/09
The Port D pins with alternate functions are shown in Table 30.
Table 30. Port D Pins Alternate Functions
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.
Table 31 relates the alternate functions of Port D to the overriding signals shown in Fig-
ure 26 on page 60.
