Description
This pin can be used for general-purpose I/
O. It can be individually programmed as
input or output and can also be used
individually as an interrupt input. Each Port
D pin, when programmed as output, can be
selected to be an open-drain or open-
source output. Port D is multiplexed with
one UART.
This pin is used by the UART to transmit
asynchronous serial data. This signal is
multiplexed with PD0.
This pin is used by the IrDA encoder/
decoder to transmit serial data. This signal
is multiplexed with PD0.
