Section 25 Flash Memory
25.2
When the mode pins are set in the reset state and reset start is performed, this LSI enters each
operating mode as shown in figure 25.2. Although the flash memory can be read in user mode, it
cannot be programmed or erased. The flash memory can be programmed or erased in boot mode,
user program mode, user boot mode, and programmer mode. The differences between boot mode,
user program mode, user boot mode, and programmer mode are shown in table 25.1.
