4. Waiting for programming/erasing command
Note that memory read of the user MAT/user boot MAT can only read the programmed data after
all user MAT/user boot MAT has automatically been erased.
After inquiries have finished, all user MAT and user boot MAT are automatically erased.
⎯ When the program preparation notice is received, the state for waiting program data is
⎯ When the erasure preparation notice is received, the state for waiting erase-block data is
⎯ There are many commands other than programming/erasing. Examples are sum check,
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.
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 used when the specified block is
programmed without a reset start 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.
blank check (erasure check), and memory read of the user MAT/user boot MAT and
acquisition of current status information.
