Section 20 Flash Memory (0.35-μm F-ZTAT Version)
20.2
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 20.2. 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 20.1. Figure 20.3
shows boot mode. Figure 20.4 shows user program mode.
