Part IV. Communications Processor Module
For synchronous communication, the internal clock is identical to the baud-rate output. To
get the preferred rate, select the system clock according to the following:
Sync Baud Rate
For example, to get a rate of 64 kbps, the system clock can be 24.96 MHz,
BRGCx[DIV16] = 0, and BRGCx[CD] = 389.
