The internal structure of each SCC channel consists of a transmit protocol machine
clocked with the transmit frequency f
receive frequency f
The clocks f

clock mode frequencies can or must be divided by 16 as selected by the Bit Clock
Rate bit CCR0L:BCR:
When bit clock rate is ‘16’ (bit BCR = ’1’), oversampling (3 samples) in conjunction
with majority decision is performed. BCR has no effect when using clock mode 2,
3a, 4, 5, 6, or 7a.
