Open-drain signal that serves as the data input/output for the I
interface.
Event input to the DMA timer modules.
Programmable output from the DMA timer modules.
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.
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.
Indicate to the UART modules that they can begin data transmission.
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.
