3. RST# at GND±0.2V ensures the lowest power consumption.
4. Command writes involving block erase, full chip erase, (page buffer) program or OTP program are reliably executed

during a write operation.
6. Never hold OE# low and WE# low at the same timing.
7. Refer to Appendix of LH28F640BF series for more information about query code.
