18.6.2
When set to the user program mode, user’s programming/erasing control program can erase and
program the flash memory. Therefore, on-chip flash memory on-board programming can be
performed by providing a means of controlling FWE and supplying the write data on the board
and providing a programming/erasing program in a part of the program area.
To select this mode, activate H8/3048F-ONE to on-chip flash memory enable modes 5, 6, and 7
and apply a high level to the FWE pin. In this state, the peripheral functions, other than flash
memory, are performed the same as in modes 5, 6, and 7.

the microcomputer’s operating mode will change and the state of the address dual port and bus
control output signals (CSn, RD, HWR, LWR) changes, use of these pins as output signals
during reset must be disabled outside the microcomputer.
Do not input low level to the FWE pin while the boot program is executing and when
