transmission.
Automatic UART request to send
outputs.
Provide the external interface to the
timer A functions.
Provide the external interface to the
timer B functions.
Clear the timer’s clock, providing a
means of synchronization to externally
clocked or timed events.
Clock the event counter or provide a
trigger to timer value capture logic.
Direct analog input ANn, or
multiplexed input ANx.
multiplexed output MAn. MAn selects
the output of the external multiplexer.
Direct analog input ANn, or input
TRIGn. TRIGn causes one of the two
queues to execute.
Selects between multiplexed debug
module and JTAG signals at reset.
Development serial clock for the serial
interface to debug module (DSCLK).
Asynchronously resets the internal
JTAG controller to the test logic reset
state (TRST).
Signals a hardware breakpoint in
debug mode (BKPT). Provides
information that determines JTAG test
operation mode (TMS).
Signals UART that it can begin data
Pulse or toggle on timer events.
