74 / 364 page ![]() 74 8023F–AVR–07/09 ATmega325P/3250P 13.3.2 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. Table 13-7 relates the alternate functions of Port D to the overriding signals shown in Figure 13- 5 on page 69. Table 13-6.
