After boot mode is initiated, the bit rate of the SCI interface is adjusted with that of the host.
For inquiries about user-MAT size and configuration, MAT start address, and support state, the
required information is transmitted to the host.
After inquiries have finished, all user MAT and user boot MAT are automatically erased.
The programming start address and program data must be transmitted following the
programming command. When programming is finished, the programming start address must
be set to H'FFFFFFFF and transmitted. Then the state for waiting program data is returned to
the state of programming/erasing command wait.
entered. The erase-block number must be transmitted following the erasing command. When
the erasure is finished, the erase-block number must be set to H'FF and transmitted. Then the
state for waiting erase-block data is returned to the state for waiting programming/erasing
command. The erasure must be executed when reset start is not executed and the specified
block is programmed after programming is executed in boot mode. When programming can be
executed by only one operation, all blocks are erased before the state for waiting
programming/erasing/other command is entered. The erasing operation is not required.
