1. In auto-programming mode, 128-byte simultaneous programming is performed. In this
2. Data transfer of 128 bytes must be performed even in the programming of 128 bytes or less.
3. Lower seven bits of the address to be transferred should be set to low. When an address other

5. Do not write commands while programming is in progress.
6. One time automatic programming should be performed for each 128-byte block of address.
7. To confirm the end of automatic programming, check the signal on I/O6 pin. Confirmation in

20.9.5
1. In auto-erase mode, only erasing the entire memory is supported.
2. Command writing should not be preformed during automatic erasing.
3. To confirm the end of automatic erasing, check the signal on the I/O6 pin. Confirmation in

status-read mode is also possible. (Status polling of the I/O7 pin is used to check the end
status of automatic programming.)
as no command is written, the information can be read by enabling the CE and OE.
