16. Communications Prescaler Register
This register controls machine clock division.
Output from the communications prescaler register is used for UART0 (SCI), UART1 (SCI), and extended I/O
serial interface.
The communications prescaler register is so designed that a constant baud rate may be acquired for various
machine clocks.
