6.2.7.3 Reset Counter Value
The counter values can be reset with external signal by configuring the Z pin as the
reset input. The reset signal can be triggered by encoder Z signal or any external
sensor's signal.
To use the reset feature, please follow the steps below:
Configuration:
Set Enable_Z_Pulse_Reset (0x8000:02) to 1 (Enable).

Define Z_And_Gate_Active_Polarity (0x8000:03) as 0 (Rising Edge Active) or 1

(Falling Edge Active).
Enable Input:
Step1: Set Enable_Latch_Z (0x7000:01) to True.
Step2: Any reset signal from Z pin, the Counter_Value (0x6000:11) will be cleared.
Step3: Once counter value is cleared, Latch_Z_Valid (0x6000:01) will be raised to
True.
Step4: Set Enable_Latch_Z (0x7000:01) to False to clear the flag for next input.
* When the reset is done, do the Step1 before next reset signal comes.
