1. 1. Set XA1, XA0 to “00”. This enables address loading.
2. Set BS1 to “1”. This selects high address.
3. Set DATA = Address High Byte ($00 - $1F).
4. Give XTAL1 a positive pulse. This loads the address High Byte.
1. Give WR a negative pulse. This starts programming of the entire page of
2. Wait until RDY/BSY goes high.
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
