19.8.2
When set to user program mode, the chip can program and erase its flash memory by executing a user program/erase
control program. Therefore, on-board reprogramming of the on-chip flash memory can be carried out by providing on-
board means of FWE control and supply of programming data, and storing a program/erase control program in part of the
program area as necessary.
To select user program mode, select a mode that enables the on-chip flash memory (mode 6 or 7), and apply a high level
to the FWE pin. In this mode, on-chip supporting modules other than flash memory operate as they normally would in
modes 6 and 7.
The flash memory itself cannot be read while the SWE bit is set to 1 to perform programming or erasing, so the control
program that performs programming and erasing should be run in on-chip RAM or external memory.
Figure 19-18 shows the procedure for executing the program/erase control program when transferred to on-chip RAM.

If the mode pin input levels are changed (for example, from low to high) during a reset, the state of ports with
multiplexed address functions and bus control output pins (AS, RD, HWR) will change according to the change in the
microcomputer’s operating mode*
Therefore, care must be taken to make pin settings to prevent these pins from becoming output signal pins during a
reset, or to prevent collision with signals outside the microcomputer.
