Applies to Bypass mode and Non-bypass mode.
Applies after power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 2000 CLKIN cycles, while
SSELx, MSELx and DF values can change from this point, but the values must be valid.
SSELx, MSELx and DF values must be held from this time, until the hold time expires.
