A programming selection command makes the boot program select the programming method, an
128-byte programming command makes it program the memory with data, and an erasing
selection command and block erasing command make it erase the block. The programming/
erasing commands are listed below.
Table 21.9 Programming/Erasing Commands
• Programming
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 ROMs. The programming selection command is user ROM
programming selection, regardless of the area and method for programming.
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.
