Section 23 Flash Memory
On receiving the command with H'FF as the block number, the boot program stops erasure
processing and waits for the next programming/erasure selection command.
To perform erasure again after having issued the command with the block number specified as
H'FF, execute the process from the selection of erasure.
• Memory read
In response to the memory read command, the boot program returns the data from the specified
address.
