Figure 22.
Double/Quadruple Byte Program flowchart and pseudo code (FWH mode
only)
1.
A Status check of SR3 (VPP Invalid) and SR4 (Program Error) can be made after each program operation
by following the correct command sequence.
2.
If an error is found, the Status Register must be cleared before further Program/Erase operations.
3.
A0 and/or A1 are treated as Don’t Care (A0 for Double Byte Program and A1-A0 for Quadruple Byte
Program).
For Double Byte Program: Starting at the Start Address, the first data Byte is programmed at the even
address, and the second at the odd address.
For Quadruple Byte Program: Starting at the Start Address, the first data Byte is programmed at the
address that has A1-A0 at 00, the second at the address that has A1-A0 at 01, the third at the address that
has A1-A0 at 10, and the fourth at the address that has A1-A0 at 11.

Double/Quadruple Byte Program command:
– write 40h or 10h
– write Start Address and 2/4 Data Bytes (3)
(memory enters read status state after
the Double/Quadruple Byte Program command)
do:
– Read Status Register
– If SR7=0 and a Program/Erase Suspend
command has been executed
– SR7 is set to 1
– Enter suspend program loop
If SR3 = 1, VPP invalid error:
– error handler
If SR4 = 1, Program error:
– error handler
