Figure 15-11 ASC Baudrate Generator Circuitry in Asynchronous Modes
Using the fixed Input Clock Divider
The baudrate for asynchronous operation of serial channel ASC when using the fixed
input clock divider ratios (S0CON_FDE=0) and the required reload value for a given
baudrate can be determined by the following formulas :
