RESET Operations
RESET Operations
RESET ENABLE and RESET MEMORY Command
To reset the device, the RESET ENABLE command must be followed by the RESET
MEMORY command. To execute each command, S# is driven LOW. The command code
is input on DQ0. A minimum de-selection time of ^tSHSL2 must come between the RE-
SET ENABLE and RESET MEMORY commands or a reset is not guaranteed. When these
two commands are executed and S# is driven HIGH, the device enters a power-on reset
condition. A time of ^tSHSL3 is required before the device can be re-selected by driving
S# LOW. It is recommended that the device exit XIP mode before executing these two
commands to initiate a reset.
All volatile lock bits, the volatile configuration register, the enhanced volatile configura-
tion register, and the extended address register are reset to the power-on reset default
condition. The power-on reset condition depends on settings in the nonvolatile config-
uration register.
If a reset is initiated while a WRITE, PROGRAM, or ERASE operation is in progress or
suspended, the operation is aborted and data may be corrupted.
