The device defaults to output SR data after the Buffered Programming Setup command (E8h) is issued. CE# or OE# must
be toggled to update Status Register. Don’t issue the Read SR command (70h), which would be interpreted by the internal
state machine as Buffer Word Count.
- Perform Read Operation
- Read Ready Status on signal SR.7
- Address = block address
- Data = word count minus 1
- Fill write buffer up to word count
- Address = within buffer range
- Data = User data
