18.4.2
When set to the user program mode, this LSI can erase and program its flash memory by executing
a user program. 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
write program in a part of the program area.
To select this mode, set the LSI to on-chip ROM enable modes 5 and 7 and apply a high level to
the FWE pin. In this mode, the peripheral functions, other than flash memory, are performed the
same as in modes 5 and 7.
In mode 6, do not program/erase the flash memory. When setting mode 6, always input low level
to the FWE pin.
Since the flash memory cannot be read while it is being programmed/erased, place a programming
program on external memory, or transfer the programming program to RAM area, and execute it
in the RAM.
Figure 18.9 shows the procedure for executing when transferred to on-chip RAM. During reset
start, starting from the user program mode is possible.
User Program Mode
flash memory and flash memory R versions of the H8/3037 requires a minimum of 20
system clocks.
