[7:6] SCP[1:0] First SCI Prescaler
These 2 prescaling bits allow several standard clock division ranges (see
Table 29).
[5:3] SCT[2:0] SCI Transmitter rate divisor
These 3 bits, in conjunction with the SCP1 & SCP0 bits define the total division
applied to the bus clock to yield the transmit rate clock (see Table 30).
[2:0] SCR[2:0] SCI Receiver rate divisor.
These 3 bits, in conjunction with the SCP[1:0] bits define the total division applied
to the bus clock to yield the receive rate clock (see Table 31).
