Section 21 Flash Memory
Where the sequence of programming operations that is executed includes programming with
another method or of another ROM, the procedure must be repeated from the programming
selection command.
The sequence for programming-selection and 128-byte programming commands is shown in
figure 21.12.
(a)
The boot program will transfer a program for programming. The data is programmed to the user
ROMs by the transferred program for programming.
• Command, H'43, (1 byte): User-program programming selection
• Response, H'06, (1 byte): Response to user-program programming selection
• Error response, H'C3, (1 byte): Error response for user-program programming selection
• ERROR: (1 byte): Error code
