Command
When CS# is driven high, the device transitions from DP mode to the standby mode after a delay of t
previously described. The RES command always provides access to the Electronic Signature of the device
and can be applied even if DP mode has not been entered.
Any RES command issued while an erase, program, or WRSR operation is in progress not executed, and the
operation continues uninterrupted.
During power-up and power-down, certain conditions must be observed. CS# must follow the voltage applied
on V
(see
A pull-up resistor on Chip Select (CS#) typically meets proper power-up and power-down requirements.
