Notes: 1. RES must be kept at the VILR level referred to DC characteristics at the rising and falling edges of VCC
to guarantee data stored in the chip.
2. RES must be kept at the VIHR level referred to DC characteristics while I/O7 outputs the VOL level in the
status data polling and RDY/Busy outputs the VOL level.
