74.6.6.2 FLEXCOM USART Characteristics
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:
- 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).
