Table 31 : Commonly Used Baud Rates by Reload Value and Deviation Errors (TQFP144 devices)
Note: The deviation errors given in the Table 31 are rounded. To avoid deviation errors use a Baud rate
crystal (providing a multiple of the ASC0/SSC sampling frequency)
S0BRS = ‘0’, f
CPU
= 32MHz S0BRS = ‘1’, f
CPU
= 32MHz
