17.22.3 Operating Mode of Flash Memory
When each mode pin is set in the reset state and reset start is performed, the microcomputer enters
each operating mode as shown in figure 17.61. For the setting of each mode pin, see table 17.52.
• Flash memory cannot be read, programmed, or erased in ROM invalid mode.
• Flash memory can be read in user mode, but cannot be programmed or erased.
• Flash memory can be read, programmed, or erased on the board only in user program mode,
• Flash memory can be read, programmed, or erased by means of the PROM programmer in
user boot mode, and boot mode.
