Section 20 Flash Memory (0.18-µm F-ZTAT Version)
The sequence of new bit-rate selection is shown in figure 20.23.
(5)
The boot program will transfer the erasing program and erase the user 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 code, H'51, (one byte): Erasing error

The boot program will send ACK when the user MATs have been erased by the transferred
erasing program.
An error occurred and erasure was not completed.
