In CPU rewrite mode, the user ROM area can be programmed by the CPU writing software commands with the
MCU mounted on a board. In CPU rewrite mode, only the user ROM area shown in Figure 26.1 can be
programmed. The boot ROM area cannot be rewritten. EW0 mode and EW1 mode are provided as CPU rewrite
mode.
Table 26.3 lists specifications of EW0 mode and EW1 mode. Figures 26.4 and 26.5 show associated registers.
Figure 26.6 shows a setting procedure for EW0 mode. Figure 26.7 shows a setting procedure for EW1 mode.
Figure 26.8 shows a setting procedure to enter and exit low power mode.
