On-Board Programming Modes
When pins are set to on-board programming mode, program/erase/verify operations can be
performed on the on-chip flash memory. There are two on-board programming modes: boot mode
and user program mode. The pin settings for transition to each of these modes are shown in table
18.6. In H8/3067RF mode 6 (on-chip ROM enabled), the boot mode and user program mode
cannot be used. For the notes on FWE pin set/reset, see section 18.9 Notes on Flash Memory
Programming/Erasing.
