Reset Cycle

Note:

1. Reset-Enable (RSTEN) (66h) and Reset (RST) (99h) commands need to match standard SPI or

EQPI (Quad) mode.

2. Continue (Enhance) EB mode need to use quad Reset-Enable (RSTEN) (66h) and quad Reset (RST)

(99h) commands.

3. If user is not sure it is in SPI or Quad mode, we suggest to execute sequence as follows:

Quad Reset-Enable (RSTEN) (66h) -> Quad Reset (RST) (99h) -> SPI Reset-Enable (RSTEN) (66h)

-> SPI Reset (RST) (99h) to reset.

4. The reset command could be executed during embedded program and erase process, EQPI mode

and Continue EB mode to back to SPI mode.

5. This flow cannot release the device from Deep power down mode.

6. The Status Register Bit will reset to default value after reset done.

7. If user reset device during erase, the embedded reset cycle software reset latency will take about

28us in worst case.
