23.5
When the mode pins (MD0, MD1, and MD2) are set to on-board programming mode and the reset
start is executed, a transition is made to on-board programming mode in which the on-chip flash
memory can be programmed/erased. On-board programming mode has three operating modes:
boot mode, user boot mode, and user program mode.
Table 23.4 shows the pin setting for each operating mode.

23.5.1
In user program mode, the flash memory can be programmed by the CPU through execution of
software commands. In this mode, the user ROM and data flash can be programmed without using
a ROM programmer with the microcomputer mounted on a system board.
The programming and block erase commands should be executed only in each block area of the
user ROM and data flash.
User program mode provides the erase/write 0 mode (EW0 mode). Table 23.5 gives an overview
of the EW0 mode specifications.
