These 2 prescaling bits allow several standard clock division ranges.
00: PR prescaling factor = 1
01: PR prescaling factor = 3
10: PR prescaling factor = 4
11: PR prescaling factor = 13
These 3 bits, in conjunction with the SCP1 and SCP0 bits, define the total division
applied to the bus clock to yield the transmit rate clock in conventional baud rate
generator mode.
000: TR dividing factor = 1
001: TR dividing factor = 2
010: TR dividing factor = 4
011: TR dividing factor = 8
100: TR dividing factor = 16
101: TR dividing factor = 32
110: TR dividing factor = 64
111: TR dividing factor = 128
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 in conventional baud rate generator
mode.
000: RR dividing factor = 1
001: RR dividing factor = 2
010: RR dividing factor = 4
011: RR dividing factor = 8
100: RR dividing factor = 16
101: RR dividing factor = 32
110: RR dividing factor = 64
111: RR dividing factor = 128
