2. Block Erasure
In response to the block erasure command, the boot program erases the data in a specified block of
the user MAT.
Command H'58
Size
Block number
SUM
• Command H'58 (1 byte): Erasure of a block
• Size (1 byte): The number of characters in the block number field (fixed at 1)
• Block number (1 byte): Block number of the block to be erased
• SUM (1 byte): Checksum
Response H'06
• Response H'06 (1 byte): Response to the block erasure command
