14.3.2 Alternate Functions of Port D
The Port D pins with alternate functions are shown in the following table.
Table 14-6. Port D Pins Alternate Functions
Port Pin Alternate Function
PD7 T0 (Timer/Counter0 Clock Input)
PD6 T1 (Timer/Counter1 Clock Input)
PD5 XCK1 (USART1 External Clock Input/Output)
PD4 ICP1 (Timer/Counter1Input Capture Trigger)
PD3 INT3/TXD1 (External Interrupt3 Input or USART1 Transmit Pin)
PD2 INT2/RXD 1(External Interrupt2 Input or USART1 Receive Pin)
PD1 INT1/SDA (External Interrupt1 Input or TWI Serial Data)
PD0 INT0/SCL (External Interrupt0 Input or TWI Serial Clock)
The alternate pin configuration is as follows:
• T0 – Port D, Bit 7
T0, this is Timer/Counter0 counter source.
