NOTES:
1. BUS operations are defined in Table 2.1 and Table 2.2.
2. X=Any valid address within the device.
3. ID=Data read from identifier codes.
4. Following the Read Identifier Codes command, read operations access manufacturer, device, block lock configuration and
5. If WP# is V
6. Either 40H or 10H are recognized by the WSM as the word/byte write setup.
7. The clear block lock-bits operation simultaneously clears all block lock-bits.
8. If the permanent lock-bit is set, Set Block Lock-Bit and Clear Block Lock-Bits commands can not be done.
9. Once the permanent lock-bit is set, permanent lock-bit reset is unable.
10. Commands other than those shown above are reserved by SHARP for future device implementations and should not be
