The flash memory contains a user ROM area, with space to store microcomputer operating programs in
single-chip mode or memory expansion mode, and a separate 8-Kbyte boot ROM area. Figure 25.1 shows
a block diagram of the flash memory.
The user ROM area is divided into several blocks, each of which can be protected (locked) from program
and erase. The user ROM area can be rewritten in CPU rewrite, standard serial I/O and parallel I/O modes.
The boot ROM area is allocated in the same addresses as the user ROM area. It can only be rewritten in
parallel I/O mode (refer to 25.5 Parallel I/O Mode). A program in the boot ROM area is executed after a
hardware reset occurs while an "H" signal is applied to the CNV
to the P5
reset occurs while an "L" signal is applied to the CNV
read.
