[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).
