PS015313-0508
A Write to either the Low or High byte registers for the BRG Divisor Latch causes both
bytes to be loaded into the BRG counter and the count restarted. See
73.

Description
These bits represent the Low byte of the 16-bit Baud Rate
Generator divider value. The complete BRG divisor value is
returned by {SPI_BRG_H, SPI_BRG_L}.
