Word Count
- Address = block address
- Data = word count minus 1
(Valid range = 0x00 to 0xFF)
Read Status Register(SR)
Load Buffer
- Fill write buffer up to word count
- Address = within buffer range
- Data = User data
Confirm
- Write 0xD0

Notes:
1.
The device defaults to output SR data after the Buffered Programming Setup command (E8h) is issued. CE# and 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.
