Description
The PD3 pin can be used for GPIO. It can be
individually programmed as an input or output
and can also be used individually as an interrupt
input. Each Port D pin, when programmed as an
output, can be selected to be an open-drain or
open-source output. Port D is multiplexed with
one channel of the UZI interface.
The slave select input line is used to select a
slave device in SPI mode. This signal is
multiplexed with PD3.
The CTS0 pin carries the modem status signal to
the UART. This signal is multiplexed with PD3.
The PD4 pin can be used for GPIO. It can be
individually programmed as an input or output
and can also be used individually as an interrupt
input. Each Port D pin, when programmed as an
output, can be selected to be an open-drain or
open-source output. Port D is multiplexed with
one channel of the UZI interface.
the UART. This signal is multiplexed with PD4.
The PD5 pin can be used for GPIO. It can be
individually programmed as an input or output
and can also be used individually as an interrupt
input. Each Port D pin, when programmed as an
output, can be selected to be an open-drain or
open-source output. Port D is multiplexed with
one channel of the UZI interface.
The DSR0 pin carries the modem status signal to
the UART. This signal is multiplexed with PC5
and PD5.
