This pin can be used for GPIO. 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.
Modem control signal from UART.
This signal is multiplexed with PD2.
