58.6.2.3 FLEXCOM USART Timings

Table 58-23. FLEXCOM USART Timings
Symbol Parameter Conditions Min Typ Max Unit
fSCK SCK frequency Synchronous (SYNC=1) host or client 25 MHz
fS UART sampling clock frequency Asynchronous (SYNC=0)(1) 25 MHz
Note:
  1. The corresponding bit rate is R = fS / 8 = 3.1 Mbits/s with oversampling FLEX_US_MR.OVER=1 and R = fS / 16 = 1.5 Mbits/s with oversampling FLEX_US_MR.OVER=0. Refer to the Baud Rate Generator figure in the section Flexible Serial Communication Controller (FLEXCOM).
