Note:
1. A8=H is recommended for manufacture ID check. If a manufacture 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
