Baud Rate Selection Table for UART
Internal Baud Rate Generator (BRG)
Peripheral Clock
BRR
When the internal Baud Rate Generator is used, the Baud Rates are determined by the BRG
overflow depending on the BRL reload value, the value of SPD bit (Speed Mode) in BDRCON
register and the value of the SMOD1 bit in PCON register.
