Data Sheet
Reset/Hold Mode
The RST#/HOLD# pin provides either a hardware reset or a hold pin. From power-on, the RST#/
HOLD# pin defaults as a hardware reset pin (RST#). The Hold mode for this pin is a user selected
option where an Enable-Hold instruction enables the Hold mode. Once selected as a hold pin
(HOLD#), the RST#/HOLD# pin will be configured as a HOLD# pin, and goes back to RST# pin only
after a power-off and power-on sequence.
Reset
If the RST#/HOLD# pin is used as a reset pin, RST# pin provides a hardware method for resetting the
device. Driving the RST# pin high puts the device in normal operating mode. The RST# pin must be
driven low for a minimum of T RST time to reset the device. The SO pin is in high impedance state while
the device is in reset. A successful reset will reset the status register to its power-up state. See Table 4
for default power-up modes. A device reset during an active Program or Erase operation aborts the
operation and data of the targeted address range may be corrupted or lost due to the aborted erase or
program operation. The device exits AAI Programming Mode in progress and places the SO pin in high
impedance state.
