7. Following the third bus cycle, inputs the program sequential address and write data of "N" times. Finally, input the any
valid address within the target partition to be programmed and the confirm command (D0H). Refer to the LH28F320BX,
LH28F640BX series Appendix for details.
8. If the program operation in one partition is suspended and the erase operation in other partition is also suspended, the
suspended program operation should be resumed first, and then the suspended erase operation should be resumed next.
9. Full chip erase and OTP program operations can not be suspended. The OTP Program command can not be accepted while
the block erase operation is being suspended.
10. Following the Clear Block Lock Bit command, block which is not locked-down is unlocked when F-WP is VIL.
When F-WP is VIH, lock-down bit is disabled and the selected block is unlocked regardless of lock-down configuration.
11. Commands other than those shown above are reserved by SHARP for future device implementations and should not be
used.
