Command Name
Set the number of retrials larger than the block erasure time divided by the time (8.5 ms) for one
erase, in accordance with the time (MAX. value) required for flash memory block erasures.
The internal verify 1 command can be executed by specifying an address in the same block, but internal
verify 2 is recommended if data is written to multiple addresses in the same block.

Specific sequence
This command is used to check if data has been
correctly written to the flash memory. It is used to
check whether data has been written to an entire
block.
This command is used to check if data has been
correctly written to the flash memory. It is used to
check whether data has been written to multiple
addresses in the same block.
This command is used to erase a specified block.
Specify the block number before execution.
This command is used to check if data in a specified
block has been erased. Specify the block number,
then execute this command.
This command is used to write 1-byte data to the
specified address in the flash memory. Specify the
write address and write data, then execute this
command.
