Clock Select 1 and 0:
These bits select the clock source for the on-chip
baud rate generator.
00: φ clock (n = 0)
01: φ/4 clock (n = 1)
10: φ/16 clock (n = 2)
11: φ/64 clock (n = 3)
For the relation between the bit rate register
setting and the baud rate, see section 14.3.9, Bit
Rate Register (BRR). n is the decimal display of
the value of n in BRR (see section 14.3.9, Bit Rate
Register (BRR)).
