Memory IC FAQ

What is the default address mode upon power-up?

The device defaults to 3-Byte address mode upon power-up, indicated by the ADS bit being 0.

How is the status register protected from unintended writes?

Protection is managed via SRP0 and SRP1 bits, allowing for software, hardware (WP#), power-down lock-down, or one-time programmable protection schemes.
