Data Area Program

This command is used to program the specified data to the data area. Set the lower 2 bits to 0 for the program address
selected in this command. When the data length is shorter than 4 bytes, the data cannot be programmed. Fill the gaps
with FFh.
When the program from the selected address is successfully completed, the MCU sends a response (06h). If the SUM of
the received command does not match or an error occurs during a program operation, the MCU sends an error response.
To enter the program/erase host command wait state after the program operation ends, send 51h FFh FFh FFh FFh B4h
from the host. The MCU sends a response (06h), and enters the program/erase host command wait state.
Command 51h
SUM
Program address (4 bytes): Address for program destination
Set the lower 2 bits of the selected address to 0
Set FFFF FFFFh for end of data area program
Program data length (1 byte): Size of program data
Program data (n bytes): Program data for the data area (n = program data length, 0 for end of program)
Set data of the program data length
When the program is less than n bytes, set FFh for the missing data.
No program data for the end of data area program
SUM (1 byte): Value that is calculated so the sum of command data is 00h
Response 06h
Error response D1h
Error (1 byte): Error code
11h: SUM error
2Ah: Address error (the address is not in the selected area.)
2Bh: Program data length error
53h: Program error (the data or program data cannot be programmed.)
