1. Page Read Command
The page read command reads the specified page (256 bytes) in the flash memory sequentially one byte at a time.
Figure 1.180 shows the page read timing. To execute the page read command:
(1) Transfer the "FF
(2) Transfer addresses A
(3) From the 4th byte on, data (D
sequentially from the smallest address first, in sync with the rise of the clock.
2. Page Program Command
This command writes the specified page (256 bytes) in the flash memory sequentially one byte at a time. Figure
1.181 shows the page program timing. To execute the page program command:
(1) Transfer the "41
(2) Transfer addresses A
(3) From the 4th byte on, write data (D0-D7) for the page (256 bytes) specified by addresses A
sequentially from the smallest address first. The page is automatically written.
The page program results can be reviewed in the status register. Refer to the status register section for more
details.
Each block can be write-protected with the lock bit. Refer to the data protection function for more details. Additional
writing of previously programmed pages is not allowed.
