(12) Transition to the programming/erasure state
In response to the transition to the programming/erasure state command, the boot program
transfers the erasing program and runs it to erase any data in the user MAT and then the user boot
MAT. On completion of this erasure, the boot program returns the ACK code and enters the
programming/erasure state.
Before sending the programming selection command and data for programming, the host must
select the device, clock mode, and new bit rate for the LSI by issuing the device selection
command, clock-mode selection command, new-bit-rate selection command, and then initiate the
transition to the programming/erasure state by sending the corresponding command to the boot
program.
Command
Response
Error
response
 Command H'40 (1 byte): Transition to programming/erasure state
 Response H'06 (1 byte): Response to the transition-to-programming/erasure state command
 Error response H'C0 (1 byte): Error response to the transition-to-programming/erasure state
 ERROR (1 byte): Error code
This is returned as ACK when erasure of the user boot MAT and user MAT has succeeded
after transfer of the erasure program.
command
H'51: Erasure error (Erasure did not succeed because of an error.)
