11.1.7.3 Flexible Serial Communication Controller (FLEXCOM) - USART

Table 11-31. FLEXCOM USART Timings
Symbol	Parameter	Conditions	Min	Max	Unit
f_SCK	SCK frequency in Synchronous mode (FLEX_US_MR.SYNC=1)	Host or client	–	25	MHz
BR	Baud rate in Asynchronous mode (FLEX_US_MR.SYNC=0)⁽¹⁾⁽²⁾	FLEX_US_MR.OVER=1	–	f_MCKx/8	Mbps
BR	Baud rate in Asynchronous mode (FLEX_US_MR.SYNC=0)⁽¹⁾⁽²⁾	FLEX_US_MR.OVER=0	–	f_MCKx/16	Mbps

Note:

MCKx stands for MCK7, MCK8 and MCK9.
With f_MCKx=100 MHz, the maximum baud rate is BR=100/8=12.5 Mbps (OVER=1) or BR=100/16=6.25 Mbps (OVER=0).
