12.1.7.2 Baudrates in Synchronous Mode
For synchronous operation, the baudrate generator provides a clock with 4 times the rate
of the established baudrate.(see Figure 87).
Figure 87
The baudrate for synchronous operation of serial channel ASC can be determined by the
formulas as shown in Table 62.
Table 62
BG represents the content of the reload register S0BR (BR_VALUE), taken as unsigned
13-bit integers.
The maximum baudrate that can be achieved in synchronous mode when using a
module clock of 36 MHz is 4.5 MBaud.
