Transition to Programming/Erasing State
The boot program will transfer the erasing program, and erase the user MATs and user boot MATs
in that order. On completion of this erasure, ACK will be returned and will enter the
programming/erasing state.
The host should select the device code, clock mode, and new bit rate with device selection, clock-
mode selection, and new bit-rate selection commands, and then send the command for the
transition to programming/erasing state. These procedures should be carried out before sending of
the programming selection command or program data.
Command
• Command, H'40, (one byte): Transition to programming/erasing state
Response
• Response, H'06, (one byte): Response to transition to programming/erasing state
The boot program will send ACK when the user MAT and user boot MAT have been erased
by the transferred erasing program.
Error Response
• Error response, H'C0, (one byte): Error response for user boot MAT blank check
• Error code, H'51, (one byte): Erasing error
An error occurred and erasure was not completed.

Command Error
A command error will occur when a command is undefined, the order of commands is incorrect,
or a command is unacceptable. Issuing a clock-mode selection command before a device selection
or an inquiry command after the transition to programming/erasing state command, are examples.
Error Response
• Error response, H'80, (one byte): Command error
• Command, H'xx, (one byte): Received command
