ICP1 – Port D, bit 4
ICP1 – Input Capture Pin 1: The PD4 pin can act as an input capture pin for Timer/Counter1.
INT3/TXD1 – Port D, bit 3
INT3, External Interrupt source 3: The PD3 pin can serve as an external interrupt source to the
MCU.
TXD1, Transmit Data (Data output pin for the USART1). When the USART1 Transmitter is
enabled, this pin is configured as an output regardless of the value of DDD3.
INT2/RXD1 – Port D, bit 2
INT2, External Interrupt source 2. The PD2 pin can serve as an External Interrupt source to the
MCU.
RXD1, Receive Data (Data input pin for the USART1). When the USART1 receiver is enabled
this pin is configured as an input regardless of the value of DDD2. When the USART forces this
pin to be an input, the pull-up can still be controlled by the PORTD2 bit.
INT1/SDA/OC2B – Port D, bit 1
INT1, External Interrupt source 1. The PD1 pin can serve as an external interrupt source to the
MCU.
SDA, 2-wire Serial Interface Data: When the TWEN bit in TWCR is set (one) to enable the 2-wire
Serial Interface, pin PD1 is disconnected from the port and becomes the Serial Data I/O pin for
the 2-wire Serial Interface. In this mode, there is a spike filter on the pin to suppress spikes
shorter than 50ns on the input signal, and the pin is driven by an open drain driver with slew-rate
limitation.
INT0/SCL/OC0B – Port D, bit 0
INT0, External Interrupt source 0. The PD0 pin can serve as an external interrupt source to the
MCU.
SCL, 2-wire Serial Interface Clock: When the TWEN bit in TWCR is set (one) to enable the 2-
wire Serial Interface, pin PD0 is disconnected from the port and becomes the Serial Clock I/O
pin for the 2-wire Serial Interface. In this mode, there is a spike filter on the pin to suppress
spikes shorter than 50ns on the input signal, and the pin is driven by an open drain driver with
slew-rate limitation.
Table 11-13 on page 85 and Table 11-14 on page 85 relates the alternate functions of Port D to
the overriding signals shown in Figure 11-5 on page 76.
