Section 20 Flash Memory
The specified address should match the unit for programming of data. For example, when the
programming is in 128-byte units, the lower byte of the address should be H'00 or H'80.
When there are less than 128 bytes of data to be programmed, the host should fill the rest with
H'FF.
Sending the 128-byte programming command with the address of H'FFFFFFFF will stop the
programming operation. The boot program will interpret this as the end of the programming and
wait for selection of programming or erasing.
• Command, H'50, (one byte): 128-byte programming
• Programming Address (four bytes): End code is H'FF, H'FF, H'FF, H'FF.
• SUM (one byte): Checksum
• Response, H'06, (one byte): Response to 128-byte programming
• Error Response, H'D0, (one byte): Error response for 128-byte programming
• ERROR: (one byte): Error code
(11) Erasure
Erasure is performed with the erasure selection and block erasure command.
Firstly, erasure is selected by the erasure selection command and the boot program then erases the
specified block. The command should be repeatedly executed if two or more blocks are to be
erased. Sending a block-erasure command from the host with the block number H'FF will stop the
erasure operating. On completion of erasing, the boot program will wait for selection of
programming or erasing.
The sequences of the issuing of erasure selection commands and the erasure of data are shown in
figure 20.28.
