Description amended
User Boot MAT Sum Check: The boot program will add the amount of data in user boot MATs and return the result.
Command H'4A
⎯ Command: H'4A (one byte): Sum check of user boot MATs
Response H'5A Size MAT checksum
SUM
⎯ Response: H'5A (one byte): Response to sum check of user boot MATs
⎯ Size (one byte): Number of characters in checksum data (fixed at 4)
⎯ MAT checksum (four bytes): Checksum of user boot MATs
The total amount of data is obtained in byte units.
⎯ SUM (one byte): Checksum (for transmit data)
User Boot MAT Checksum: The boot program will add the amount of data in user boot MATs and return the result. The
user boot MAT checksum value is calculated as a 16-Kbyte area. The checksum value is the sum of 12 Kbytes of user boot
MAT data and 4 Kbytes of H'FF data.
Command H'4A
⎯ Command: H'4A (one byte): Checksum of user boot MATs
Response H'5A Size MAT checksum
SUM
⎯ Response: H'5A (one byte): Response to checksum of user boot MATs
⎯ Size (one byte): Number of characters in checksum data (fixed at 4)
⎯ MAT checksum (4 bytes): The user boot MAT checksum value calculated by adding byte units, with a further 4
Kbytes of H'FF data added
⎯ SUM (one byte): Checksum (for transmit data)
