Boot program status inquiry
(1) Programming
Programming is executed by a programming-selection command and an 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, and selection
is according to the area and method for programming.
• User boot MAT programming selection
• User MAT programming selection
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 an 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.
Where the sequence of programming operations that is executed includes programming with
another method or of another MAT, the procedure must be repeated from the programming
selection command.
