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 1.161 shows the timing for the page read.
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 fall 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 1.162
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 (D
sequentially from the smallest address first. The page is automatically written.
When reception of the page (256 bytes) ends, the RTS1 (BUSY) signal changes from the "H" to the "L" level. The status
register shows the results of the page program. Refer to the status register section for more details.
Each block is write-protected with the lock bit. Refer to the data protection function section for more details. Additional
writing of previously programmed pages is not allowed.
