If the user programs either nibble of the Clock
Select Register (CSRn[7:4] or CSRn[3:0]) with
values ranging from 0
using the BRG as a source for timing. How-
ever, these standard bit rates (presented in
Table 15) apply only if the X1/CLK pin is driven
with a 3.6864 MHz signal. If a signal with a
different frequency (fo) is applied to the X1/CLK
pin, then the QUART channel is running at the
following baud rate:
