Page Program Command
This command writes the specified page (256 bytes) in the flash
memory sequentially one byte at a time. Execute the page program
command as explained here following.
(1) Transfer the
41
16
command code with the 1st byte.
(2)
Transfer addresses A
8
to A
15
and A
16
to A
23
(
00
16
)
with the 2nd
and 3rd bytes respectively.
(3)
From the 4th byte onward, as write data (D
0
D
7
) for the page (256
bytes) specified with addresses A
8
to A
23
is input sequentially from
the smallest address first, that page is automatically written.
__________
When reception setup for the next 256 bytes ends, the S
RDY1
(BUSY) signal changes from the
H
to the
L
level. The result of the
page program can be known by reading the status register. For
more information, see the section on the status register.
Erase All Blocks Command
This command erases the content of all blocks. Execute the erase all
blocks command as explained here following.
(1) Transfer the
A7
16
command code with the 1st byte.
(2) Transfer the verify command code
D0
16
with the 2nd byte. With
the verify command code, the erase operation will start and con-
tinue for all blocks in the flash memory.
When block erasing ends, the
S
RDY1
(BUSY) signal changes from
the
H
to the
L
level . The result of the erase operation can be
known by reading the status register.
