I. Repeat B through H until the entire Flash is programmed or until all data has been
programmed.
J. End Page Programming
1. Set XA1, XA0 to “10”. This enables command loading
2. Set DATA to “0000 0000”. This is the command for No Operation
3. Give XTAL1 a positive pulse. This loads the command, and the internal write signals are
