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