Description
Baud Rate Generator Constant
When read, returns the actual timer count value (when UCTL[0]=1).
When written, sets the Baud Rate Generator Constant.
The actual baud rate frequency = XTAL ÷ (32 x BCNST ).
The system clock is usually the crystal clock divided by 2. When the UART baud rate gen-
erator is used as an additional timer, a Read from this register returns the actual value of
the count of the BRG in progress and not the reload value. See
This register is not reset after a Stop Mode Recovery.
