In CPU rewrite mode, the user ROM area can be rewritten when the CPU executes software commands.
The user ROM area can be rewritten with the microcomputer mounted on a board without using a parallel or serial
programmer.
In CPU rewrite mode, only the user ROM area shown in Figure 22.1 can be rewritten. The boot ROM area cannot
be rewritten. Program and the block erase command are executed only in the user ROM area.
Erase-write 0 (EW0) mode and erase-write 1 (EW1) mode are provided as CPU rewrite mode. Table 22.3 lists
differences between erase-write 0 (EW0) and erase-write 1 (EW1) modes.
1. Do not generate an interrupt (except NMI interrupt) or DMA transfer.
2. 2. When in CPU rewrite mode, the PM10 and PM13 bits in the PM1 register are set to “1”. The
rewrite control program can only be executed in the internal RAM or in an external area that is
enabled for use when the PM13 bit = 1. When the PM13 bit = 0 and the flash memory is used in 4M-
byte mode, the extended accessible area (40000h to BFFFFh) cannot be used.
