7.37 Enable Reset (66H) and Reset (99H)

If the Reset command is accepted, any on-going internal operation will be terminated and the device will return to its

default power-on state and lose all the current volatile settings, such as Volatile Status Register bits, Write Enable Latch

status (WEL), Program/Erase Suspend status, Read Parameter setting (P7-P0), Deep Power Down Mode, Continuous

Read Mode bit setting (M7-M0) and Wrap Bit Setting (W6-W4).

The “Enable Reset (66H)” and the “Reset (99H)” commands can be issued in either SPI or QPI mode. The “Reset

(99H)

” command sequence as follow: CS# goes low  Sending Enable Reset command  CS# goes high  CS# goes

low  Sending Reset command  CS# goes high. Once the Reset command is accepted by the device, the device will

take approximately tRST =30us / tRST_E =12ms to reset. During this period, no command will be accepted. Data corruption

may happen if there is an on-going or suspended internal Erase or Program operation when Reset command sequence is

accepted by the device. It is recommended to check the WIP bit and the SUS bit in Status Register before issuing the

Reset command sequence.
