Description of the flash memory erasing mode
1. The 1st through 4th bytes of the transmitted and received data contain the same data as in the flash
2. The 5th byte of the received data contains the command data in the flash memory erasing mode
3. When the 5th byte of the received data contains the operation command data shown in Table 15-6,
4. The 7th thorough m'th bytes of the transmitted and received data contain the same data as in the
5. The n’th - 2 byte contains the erasure area specification data. The upper 4 bits and lower 4 bits spec-
6. The n’th - 1 byte and n’th byte contain the upper and lower bytes of the checksum, respectively.
7. After sending the checksum, the device waits for the next operation command data.

(F0H).
the device echoes back the value which is the same data in the 6th byte position of the received da-
ta (in this case, F0H). If the 5th byte of the received data does not contain the operation command da-
ta, the device enters the halt condition after sending 3 bytes of the operation command error code
(63H).
flash memory writing mode. In the case of a blank product, do not transmit a password string. (Do
not transmit a dummy password string.)
ify the start address and end address of the erasure area, respectively. For the detailed description,
see "15.13 Specifying the Erasure Area".
For how to calculate the checksum, refer to "15.8 Checksum (SUM)". Checksum is calculated un-
less a receiving error or Intel Hex format error occurs. After sending the end record, the external con-
troller judges whether the transmission is completed correctly by receiving the checksum sent by
the device.
