Section 21 Flash Memory (0.18-μm F-ZTAT Version)
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.
The sequence for programming-selection and 128-byte programming commands is shown in
figure 21.21.
(a) User boot MAT programming selection
The boot program will transfer a programming program. The data is programmed to the user boot
MATs by the transferred programming program.
