Calibration Method 1

Calibration is enabled by the flag CalEnable, which is enabled by the

control system. The preset value is copied to the counter register at a

positive edge on input Z. The old counter register value is saved in

the store register for evalution.

Calibration direction is determined by CalDirection (0 = positive

direction, 1 = negative direction).

Reset Calibrated, Stored and PresetReached after calibration with

CalReset, StoreReset and PresetReset.
