Hold Mode (HOLD#)
The Hold input (HOLD#) stops any serial communication with the device, but does not terminate any Write
Status Register, program or erase operation that is currently in progress.
The Hold mode starts on the falling edge of HOLD# if SCK is also low (see
falling edge of HOLD# does not occur while SCK is low, the Hold mode begins after the next falling edge of
SCK (non-standard use).
The Hold mode ends on the rising edge of HOLD# signal (standard use) if SCK is also low. If the rising edge
of HOLD# does not occur while SCK is low, the Hold mode ends on the next falling edge of CLK (non-
standard use) See
The SO output is high impedance, and the SI and SCK inputs are ignored (don’t care) for the duration of the
Hold mode.
CS# must remain low for the entire duration of the Hold mode to ensure that the device internal logic remains
unchanged. If CS# goes high while the device is in the Hold mode, the internal logic is reset. To prevent the
device from reverting to the Hold mode when device communication is resumed, HOLD# must be held high,
followed by driving CS# low.
