1042H–AVR–04/03
•TXD – Port D, Bit 1
Transmit Data (Data Output pin for the UART). When the UART Transmitter is enabled,
this pin is configured as an output, regardless of the value of DDD1.
• RXD – Port D, Bit 0
Receive Data (Data Input pin for the UART). When the UART Receiver is enabled, this
pin is configured as an input, regardless of the value of DDD0. When the UART forces
this pin to be an input, a logical “1” in PORTD0 will turn on the internal pull-up.
Port D Schematics
Note that all port pins are synchronized. The synchronization latches are, however, not
shown in the figures.
