I/O
Serial Clock
SCL
Open-drain clock signal for the for the I2C interface. Either it is driven
by the I2C module when the bus is in master mode or it becomes the
clock input when the I2C is in slave mode.
I/O
Serial Data
SDA
Open-drain signal that serves as the data input/output for the I2C
interface.

I/O
Transmit Serial Data
Output
UTXDn
Transmitter serial data outputs for the UART modules. The output is
held high (mark condition) when the transmitter is disabled, idle, or in
the local loopback mode. Data is shifted out, LSB first, on this pin at
the falling edge of the serial clock source.
O
Receive Serial Data
Input
URXDn
Receiver serial data inputs for the UART modules. Data is received on
this pin LSB first. When the UART clock is stopped for power-down
mode, any transition on this pin restarts it.
I
Clear-to-Send
UCTSn
Indicate to the UART modules that they can begin data transmission.
I
Request-to-Send
URTSn
Automatic request-to-send outputs from the UART modules. This
signal can also be configured to be asserted and negated as a
function of the RxFIFO level.
O
