21B.4.3 Mode Transitions
When the mode pins and the FWE pin are set in the reset state and a reset-start is executed, the
microcomputer enters an operating mode as shown in figure 21B-3. 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.

not accessing the flash memory.
1. RAM emulation possible
2. This LSI transits to programmer mode by using the dedicated PROM programmer.
