Note: The deviation errors given in the Table 29 are rounded. To avoid deviation errors use a Baud rate

crystal (providing a multiple of the ASC0/SSC sampling frequency).

Table 29 : Commonly Used Baud Rates by Reload Value and Deviation Errors (TQFP144 devices)

S0BRS = ‘0’, fCPU = 32MHz

S0BRS = ‘1’, fCPU = 32MHz
