JTAG data output pin.
JTAG reset input pin.
Ground.
This pin is used for GPIO. It is
individually programmed as input or
output and is also used individually as
an interrupt input. Each Port D pin,
when programmed as output is
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.
