ATmega162(V/U/L)
• RXD0 – Port D, Bit 0
RXD0, Receive Data (Data input pin for USART0). When the USART0 Receiver is
enabled this pin is configured as an input regardless of the value of DDD0. When
USART0 forces this pin to be an input, the pull-up can still be controlled by the PORTD0
bit.
Table 39 and Table 40 relate the alternate functions of Port D to the overriding signals
shown in Figure 32 on page 66.
