2. IF Counter Structure
The IF counter block consists of an input amp, a gate time control circuit, and a 12-
+
8-bit binary counter.
The FMin/AMin prescaler clock can be input to the IF counter.
Note: All the binary counters of the IF counter operate on the rising edge.
Note: The prescaler 1/15
16 division is fixed to 1/16 when the IF counter is input. FMin input division is 1/32;
AMin input division is 1/16 or direct input can be used.
