Memory IC FAQ

What is the function of the HOLD#/RESET# pin?

The function depends on the HOLD/RST bit in Status Register No. 3. When set to 0, it acts as a HOLD# pin to pause serial communications. When set to 1, it acts as a RESET# pin to reset the device internally.

How is Quad SPI mode enabled?

Quad SPI mode is enabled by setting the Quad Enable (QE) bit to 1 in Status Register No. 2. This reconfigures the WP# and HOLD#/RESET# pins as bidirectional I/O pins IO2 and IO3.
