• Programmer mode
• Emulation function for flash memory in RAM
20.2
When the mode pins and the FWE pin 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.

Flash memory can be programmed/erased in programmer mode using a PROM programmer,
as well as in on-board programming mode.
The real-time emulation for programming of flash memory is possible by overlapping the flash
memory to a part of RAM.
