Overview of Operation

19.4.1

Mode Transitions

When the mode pins and the FWE pin are set in the reset state and a reset-start is executed, the
H8/3062F-ZTAT B-mask version enters one of the operating modes shown in figure 19.3. In user
mode, flash memory can be read but not programmed or erased.

Flash memory can be programmed and erased in boot mode, user program mode, and PROM
mode.

Boot mode and user program mode cannot be used in the H8/3062F-ZTAT B-mask version’s
mode 6 (normal mode with on-chip ROM enabled).
