Product Specification (V1.0) 07.26.2005
(This specification is subject to change without further notice)
4.7.4 Baud Rate Generator:
The baud rate generator is comprised of a circuit that generates a clock pulse to
determine the transfer speed for transmission/reception in the UART.
The BRATE2~BRATE0 bits of the URC1 register can determine the desired baud rate.
