Mode Transitions
When the mode pins are set in the reset state and a reset-start is executed, this LSI enters an
operating mode as shown in figure 19.2. In user mode, flash memory can be read but not
programmed or erased.
The boot, user program and programmer modes are provided as modes to write and erase the flash
memory.
The differences between boot mode and user program mode are shown in table 19.1. Figure 19.3
shows boot mode. Figure 19.4 shows user program mode.
