Memory IC FAQ

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the WP# and HOLD# pins function as bidirectional I/O pins (IO2 and IO3) for Quad SPI operations. When QE is 0, these pins retain their dedicated Write Protect and Hold functions.

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit configures the number of dummy cycles between address output and data output. This adjusts latency to accommodate higher clock frequencies, ensuring stable data retrieval during fast read commands.
