correction.
25.2 Configuration of ROM Correction
The
Program bugs found in the flash memory can be avoided, and program flow can be changed by using the ROM
The ROM correction can correct two places (max.) of the internal flash memory (program).
Caution The ROM correction cannot be emulated by the in-circuit emulator.
The ROM correction includes the following hardware.
Figure 25-1 shows a block diagram of the ROM correction.
