Function
Transmit Clock Channel A
The function of this pin depends on the selected
clock mode and the value of bit ’TOE’
register, refer to
SCCs" on Page
If programmed as Input (CCR0L.TOE=’0’),
either
– the transmit clock for the channel (clock
– a transmit strobe signal for the channel (clock
can be provided to this pin.
If programmed as Output (CCR0L.TOE=’1’),
this pin supplies either
– the transmit clock from the baud rate generator
– the transmit clock from the DPLL circuit (clock
– an active-low control signal marking the
Receive Clock Channel A
The function of this pin depends on the selected
clock mode (refer to
the SCCs" on Page
A signal provided on pin RxCLKA may supply
– the receive clock (clock mode 0, 4, 5b), or
– the receive and transmit clock (clock mode 1,
– the clock input for the baud rate generator
mode 0a, 2a, 4, 5b, 6a), or
mode 1)
(clock mode 0b, 2b, 3b, 6b, 7b), or
mode 3a, 7a), or
