PC1
GPIO Port C
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 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.
RxD1
PC2
Receive Data Input
This pin is used by the UART to receive
asynchronous serial data. This signal is
multiplexed with PC1.
78
GPIO Port C
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 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.
RTS1
PC3
Request to
Send
Output, Active Low
Bidirectional
Modem control signal from UART.
This signal is multiplexed with PC2.
79
GPIO Port C
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.
CTS1
Clear to Send Input, Active Low
Modem status signal to the UART.
This signal is multiplexed with PC3.
