Section 23 Flash Memory
23.2.2
When each mode pin and the FWE pin are set in the reset state and the reset signal is released, the
microcomputer enters each operating mode as shown in figure 23.2. For the setting of each mode
pin and the FWE pin, see table 23.1.
• Flash memory cannot be read, programmed, or erased in ROM invalid mode. The
• 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
