Memory IC FAQ

What is the purpose of the QE bit in the status register?

The Quad Enable (QE) bit allows the device to operate in Quad SPI mode. When set, pins WP# and HOLD# function as bidirectional I/O pins IO2 and IO3.

How does the hold function operate?

The hold function pauses serial communication without resetting internal logic. It requires CS# to remain low and activates on the falling edge of the HOLD# signal while SCLK is low.
