The sequence of new bit-rate selection is shown in figure 24.21.
(5)
The boot program will transfer the erasing program and erase the data in the user MATs first , then
the data in the user boot MATs. On completion of this erasure, ACK will be returned and the
program 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
Error Response
• Error response, H'C0, (one byte): Error response to the bland check of the user boot MATs
• Error code, H'51, (one byte): Erasing error
The boot program will send ACK when the user MATs and the user boot MATs have been
erased by the transferred erasing program.
An error occurred and erasure was not completed.
