11.1.7.3 Flexible Serial Communication Controller (FLEXCOM) - USART

Table 11-30. FLEXCOM USART Timings
Symbol	Parameter	Conditions	Min	Typ	Max	Unit
f_SCK	SCK frequency	Synchronous (SYNC=1) host or client	–	–	25	MHz
f_S	UART sampling clock frequency	Asynchronous (SYNC=0)⁽¹⁾	–	–	25	MHz

Note:

The corresponding bit rate is R = f_S / 8 = 3.1 Mbits/s with oversampling FLEX_US_MR.OVER=1 and R = f_S / 16 = 1.5 Mbits/s with oversampling FLEX_US_MR.OVER=0. Refer to the figure "Baud Rate Generator" in the section Flexible Serial Communication Controller (FLEXCOM).
