Section 21 Flash Memory
• Command H'52 (1 byte): Memory read
• Size (1 byte): The total length of the area, address for reading, and amount to read fields (fixed
value of 9)
• Area (1 byte):
H'00: User boot MAT
H'01: User MAT
An incorrect area specification will produce an address error.
• Address where reading starts (4 bytes)
• Amount to read (4 bytes): The amount of data to be read
• SUM (1 byte): Checksum

• Error response H'D2 (1 byte): Error response to memory read command
• ERROR (1 byte): Error code
H'11: Sum-check error
H'2A: Address error (the address specified for reading is beyond the range of the MAT)
H'2B: Size error (the specified amount is greater than the size of the MAT,
the last address for reading as calculated from the specified address for the start of reading and
the amount to read is beyond the MAT area, or "0" was specified as the amount to read)
