23.3.3 Port pins
When the flash memory programming mode is set, all the pins not used for flash memory programming enter the same
status as that immediately after reset. If external devices connected to the ports do not recognize the port status
immediately after reset, the port pin must be connected to either to V
23.3.4 REGC pin
Connect the REG C pin to GND via a capacitor having excellent characteristics (0.47 to 1
during normal operation. Also, use a capacitor with good characteristics, since it is used to stabilize internal voltage.
23.3.5 X1 and X2 pins
Connect X1 and X2 in the same status as in the normal operation mode.
Remark In the flash memory programming mode, the high-speed on-chip oscillator clock (f

To use the on-board supply voltage, connect in compliance with the normal operation mode.
However, when writing to the flash memory by using the flash memory programmer and using the on-board supply
voltage, be sure to connect the V
monitor function with the flash memory programmer.
