PD6
GPIO Port D
Bidirectional
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.
DCD0
PD7
Data Carrier
Detect
Input, Active Low
Bidirectional
Modem status signal to the UART.
This signal is multiplexed with PD6.
GPIO Port D
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.
RI0
Ring Indicator Input, Active Low
GPIO Port C Bidirectional
Modem status signal to the UART.
This signal is multiplexed with PD7.
PC0
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 C pin,
when programmed as output, can be
selected to be an open-drain or open-
source output. Port C is multiplexed with
one UART.
TxD1
Transmit Data Output
This pin is used by the UART to transmit
asynchronous serial data. This signal is
multiplexed with PC0.
