SC0BDH and SC0BDL are considered together as a 16-bit baud rate
control register.
Read any time. Write SBR[12:0] anytime. Low order byte must be written
for change to take effect. Write SBR[15:13] only in special modes.
The value in SBR[12:0] determines the clock rate of the MI Bus. The
desired baud rate is determined by the following formula:
BR is the value written to bits SBR[12:0] to establish baud rate.
The baud rate generator is disabled until TE or RE bit in SC0CR2
register is set for the first time after reset, and/or the baud rate generator
is disabled when SBR[12:0] = 0.
BTST — Reserved for test function
BSPL — Reserved for test function
BRLD — Reserved for test function
Read or write anytime.
WOMS — Wired-Or Mode for Serial Pins
This bit controls the two pins (TxD0 and RxD0) associated with the
SC0 section.
0 = Pins operate in a normal mode with both high and low drive
1 = Each pin operates in an open drain fashion if that pin is
