7.4.1.6 CLOCK-SELECT REGISTER (CSR). The CSR selects the baud rate clock for the
channel receiver and transmitter. This register can only be written when the serial module
is enabled (i.e., the STP bit in the MCR is cleared).
RCS3–RCS0—Receiver Clock Select
7-26
These bits select the baud rate clock for the channel receiver from a set of baud rates
listed in Table 7-4. The baud rate set selected depends upon the auxiliary control
register (ACR) bit 7. Set 1 is selected if ACR bit 7 = 0, and set 2 is selected if ACR bit
7 = 1. The receiver clock is always 16 times the baud rate shown in this list, except
when SCLK is used.
This register should only be written after the external crystal is
stable (XTAL_RDY bit of the ISR is zero).
