Note 1. When MSD (Mark detection) is assigned to the CN1-10 pin with [Pr. PD44], current position data can be obtained in high
speed (within 0.4 ms). When assigning MSD (Mark detection) to the CN1-10 pin, set "Mark detection fast input signal filter
selection" in [Pr. PD31].
2. The position data will not be changed from the previous value.
3. MSDH (Latch completed at rising edge of mark detection) turns off at the same timing as MSDL (Latch completed at falling
edge of mark detection) turns on. Set as MSDL turns on/off within the range of the latch data.
If MSD (Mark detection) was turned on again when the previous falling was out of the valid range,
MSDH (Latch completed at rising edge of mark detection) will not change, but the position data will be
updated. Refer to the following timing chart.
