4. Waiting for programming/erasing command
• When the program preparation notice is received, the state for waiting program data is
entered. 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.
• When the erasure preparation notice is received, the state for waiting erase-block data is
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.
• There are many commands other than programming/erasing. Examples are sum check, blank
check (erasure check), and memory read of the user MAT/user boot MAT and acquisition of
current status information.
Note that memory read of the user MAT/user boot MAT can only read the program data after all
user MAT/user boot MAT has automatically been erased.
