fSCK

SCK frequency in Synchronous mode

(FLEX_US_MR.SYNC = 1)

Host or client–25MHz
BR

Baud rate in Asynchronous mode(1)

(FLEX_US_MR.SYNC = 0) 		FLEX_US_MR.OVER = 1–max (fMCK/8, 25)Mbps
FLEX_US_MR.OVER = 0–fMCK/16
Note:
  1. With fMCK = 266 MHz, the maximum baud rate is BR = 25 Mbps (OVER = 1) or BR = 266/16 = 16.6 Mbps (OVER = 0).
