Set DATA = Address high byte (0x00 - 0xFF).

Give XTAL1 a positive pulse. This loads the address high byte.

H. Program Page

Give WR a negative pulse. This starts programming of the entire page of data.

RDY/BSY goes low.

Wait until RDY/BSY goes high (See Figure 21-3 for signal waveforms).

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 “1,0”. This enables command loading.
