The number of DIV bits for each generic clock is as shown in the “Generic Clock number of DIV bits” table in the SCIF Module
Configuration section.
Selects the source clock for the generic clock. Please refer to the “Generic Clock Sources” table in the SCIF Module
Configuration section.
0: The generic clock equals the undivided source clock.
1: The generic clock equals the source clock divided by 2*(DIV+1).
0: The generic clock is disabled.
1: The generic clock is enabled.
