NOTES:
1. Following the Read Identifier or CFI Query commands, read operations output device identification data or
CFI query information, respectively. See Section 4.1.2 and Section 4.1.3.
2. Either 0x40 or 0x10 command is valid, but the Intel standard is 0x40.
3. When writing commands, the upper data bus [DQ8-DQ15] should be either VIL or VIH, to minimize current
draw.
