When set to user program mode, the H8/3048F can erase and program its flash memory by
executing a user program. On-board updates of the on-chip flash memory can be carried out by
providing on-board circuits for supplying V
the program area.
To select user program mode, select a mode that enables the on-chip ROM (mode 5, 6, or 7) and
apply 12 V to the V
would in mode 5, 6, or 7, except for the flash memory. A watchdog timer overflow, however,
cannot output a reset signal while 12 V is applied to V
bit (RSTOE) should not be set to 1.
The flash memory cannot be read while being programmed or erased, so the update program must
either be stored in external memory, or transferred temporarily to the RAM area and executed in
RAM.
