Note
A connector must be mounted on the target system to connect the flash
programmer for on-board writing. In addition, functions to switch between the
normal operation mode and flash memory programming mode and to control
the microcontroller's reset pin must be provided on the board.
When the flash memory programming mode is set, all the pins not used for
flash memory programming are in the same status as immediately after reset.
If the PG-FP4 is used as the flash programmer, it generates the signals listed
in Table 7-4 for the microcontroller. For details, refer to the PG-FP4 User's
Manual (U15260E).
