7.4.1
7.4.1.1
Separate, externally generated receive and transmit clocks are supplied to the SCC via
their respective pins. The transmit clock may be directly supplied by pin TxCLK
(clock mode 0a) or generated by the internal baud rate generator from the clock supplied
at pin XTAL1 (clock mode 0b).
In clock mode 0b the resulting transmit clock can be driven out to pin TxCLK if enabled
via bit ’TOE’ in register CCR2.
