Note:
1. A8=H is recommended for Manufacturing ID check. If a manufacturing ID is read with A8=L, the chip will output a
configuration code 7Fh
2. A9 = VID is for HV A9 Autoselect mode only. A9 must be
≤
Vcc (CMOS logic level) for Command Autoselect Mode.
This Data Sheet may be revised by subsequent versions
