NOTES:
1. BUS operations are defined in Table 3 and Table 3.1.
2. X=Any valid address within the device.
3. SRD=Data read from status register. See Table 14 for a description of the status register bits.
4. Following the Read Identifier Codes command, read operations access manufacturer, device and block status
5. If the block is locked, WP# must be at V
6. Either 40H or 10H are recognized by the WSM as the byte write setup.
7. A block lock-bit can be set while WP# is V
8. WP# must be at V
9. Following the Third Bus Cycle, inputs the write address and write data of ’N’ times. Finally, input the confirm
10. Commands other than those shown above are reserved by SHARP for future device implementations and
