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.
Modem status signal to the UART. This
signal is multiplexed with PD3.
