A
This command downloads a program to the RAM for execution. Execute the download command as
explained here following.
When all data has been transmitted, if the check sum matches, the downloaded program is executed.
The size of the program will vary according to the internal RAM.
This command disables the lock bit. The command code “75
transmission. This command only disables the lock bit function; it does not set the lock bit itself.
However, if an erase command is executed after executing the lock bit disable command, “0” (locked)
lock bit data is set to “1” (unlocked) after the erase operation ends. In any case, after the reset is
cancelled, the lock bit is enabled.
