19.2
When the mode pin and the FWP pin 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 PROM 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, and figure 19.4 shows user program mode.
