Programming is executed by a programming-selection command and a 128-byte programming
command.
Firstly, the host should send the programming-selection command and select the programming
method and programming MATs. There are two programming selection commands according
to the area and method for programming.
(1) User boot ROM programming selection
(2) User ROM programming selection (including the data flash)
After issuing the programming selection command, the host should send the 128-byte
programming command. The 128-byte programming command that follows the selection
command represents the data programmed according to the method specified by the selection
command. When more than 128-byte data is programmed, 128-byte commands should
repeatedly be executed. Sending a 128-byte programming command with H'FFFFFFFF as the
address will stop the programming. On completion of programming, the boot program will
wait for selection of programming or erasing.
