Programming is executed by the programming selection and 128-byte programming
commands.
Firstly, the host should send the programming selection command.
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.
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.
The sequence for the programming selection and 128-byte programming commands is shown
in figure 24.22.
