(6)
The boot program will transfer the erasing program, and erase the user ROMs. On completion of
this erasure, ACK will be returned and the programming/erasing state will be entered.
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, H'40, (1 byte): Transition to programming/erasing state
• Response, H'06, (1 byte): Response to transition to programming/erasing state
• Error code, H'51, (1 byte): Erasure error
(7)
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, H'80, (1 byte): Command error
• Command, H'xx, (1 byte): Received command
