maximum. It is set by eight bits in terms of software. However, the actual circuit uses 10-bit counter with the low-
order two bits fixed to “0”. Therefore, the number of pulses that is actually generated during fall edge of the first point
wait time + first point magnetize wait time (FF2) cycle is the number of pulses input
be set in a range of 0 to 1020 and in units of four pulses.

Data
Remark If D0 to D4 bits input “00000” to “01010”, EVR value fixed 50 mV (FIL pin voltage fixed 100 mV).
The 10th byte sets pulse number during 1V
