Description
Power Supply.
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.
This pin can be used for general-purpose

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 receive
asynchronous serial data. This signal is
multiplexed with PD1.
