7.32 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 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 / tRST_E 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 BUSY bit and the SUS bit in Status Register before issuing the Reset command sequence.
