(a) Erasure Selection
The boot program will transfer the erasure program. User MAT data is erased by the transferred
erasure program.
• Command, H'48, (one byte): Erasure selection
• Response, H'06, (one byte): Response for erasure selection
• Error Response, H'C8, (one byte): Error response to erasure selection
• ERROR: (one byte): Error code
(b) Block Erasure
The boot program will erase the contents of the specified block.
• Command, H'58, (one byte): Erasure
• Size (one byte): The number of bytes that represents the erasure block number
• Block number (one byte): Number of the block to be erased
