22.6.2
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 an on-board means of supplying 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 2 or 3).
In this mode, on-chip supporting modules other than flash memory operate as they normally
would in mode 2 and 3.
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 22.11 shows the procedure for executing the program/erase control program when
transferred to on-chip RAM.
Note: The watchdog timer should be activated to prevent overprogramming or overerasing
