Section 25 Flash Memory
1. After SCI boot mode is initiated, the bit rate of the SCI_4 is adjusted with that of the host.
2. Inquiry information about the size, configuration, start address, and support status of the user
3. After inquiries have finished, all user MAT and user boot MAT are automatically erased.
4. When the program preparation notice is received, the state of waiting for program data is
Memory read of the user MAT/user boot MAT can only read the data programmed after all user
MAT/user boot MAT has automatically been erased. No other data can be read.

MAT is transmitted to the host.
entered. The start address of the programming destination and program data must be
transmitted after the programming command is transmitted. When programming is finished,
the start address of the programming destination must be set to H'FFFFFFFF and transmitted.
Then the state of waiting for program data is returned to the state of waiting for
programming/erasing command. When the erasure preparation notice is received, the state of
waiting for erase block data is entered. The erase block number must be transmitted after the
erasing command is transmitted. When the erasure is finished, the erase block number must be
set to H'FF and transmitted. Then the state of waiting for erase block data is returned to the
state of waiting for programming/erasing command. Erasure must be executed when the
specified block is programmed without a reset start after programming is executed in SCI boot
mode. When programming can be executed by only one operation, all blocks are erased before
entering the state of waiting for programming/erasing command or another command. Thus, in
this case, the erasing operation is not required. The commands other than the
programming/erasing command perform sum check, blank check (erasure check), and memory
read of the user MAT/user boot MAT and acquisition of current status information.
