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

H'40

• Command H'40 (1 byte): Transition to programming/erasure state

Response

H'06

• Response H'06 (1 byte): Response to the transition-to-programming/erasure state command

This is returned as ACK when erasure of the user boot MAT and user MAT has succeeded

after transfer of the erasure program.

Error

response

H'C0

H'51

• Error response H'C0 (1 byte): Error response to the transition-to-programming/erasure state

command

• ERROR (1 byte): Error code

H'51: Erasure error (Erasure did not succeed because of an error.)
