There are two groups of clock dividers, Digital and Analog.

When a Clock is put on the PSoC Creator's schematic,

GS004352.png

the clock domain is selected from DIGITAL and ANALOG

GS004353.png

Once the clock is attached to the Counter component,

GS004354.png

the clock domain is fixed to DIGITAL.

If you didn't see any error on PSoC Creator, the clock can be used as the FF-type Counter clock.
