(a)
The boot program will transfer a program for programming in response to the user boot ROM
programming selection. The data is programmed to the user boot ROM areas by the transferred
program for programming.
• Command, H'42, (1 byte): User boot ROM programming selection
• Response, H'06, (1 byte): Response to user boot ROM programming selection

Command
Response
Where the sequence of programming operations that is executed includes programming with
another method or of another MAT, the procedure must be repeated from the programming
selection command.
The sequence for programming-selection and 128-byte programming commands is shown in
figure 23.17.
When the programming program has been transferred, the boot program will return ACK.
