CHAPTER 2 PIN FUNCTIONS
Preliminary User’s Manual U17397EJ2V1UD
38
2.2.13 AVSS
This is the A/D converter ground potential pin. Even when the A/D converter is not used, always use this pin with
the same potential as the VSS pin.
2.2.14 RESET
This is the active-low system reset input pin.
2.2.15 REGC
This is the pin for connecting regulator output (2.5 V) stabilization capacitance for internal operation. Connect this
pin to VSS via a capacitor (0.47
F: target).
REGC
VSS
Caution
Keep the wiring length as short as possible for the broken-line part in the above figure.
2.2.16 VDD and EVDD
VDD is the positive power supply pin for other than P121 to P124 and ports.
EVDD is the positive power supply pin for ports other than P20 to P27 and P121 to P124.
2.2.17 VSS and EVSS
VSS is the ground potential pin for other than P121 to P124 and ports.
EVSS is the ground potential pin for ports other than P20 to P27 and P121 to P124.
2.2.18 FLMD0
This is a pin for setting flash memory programming mode.
Connect FLMD0 to EVSS or VSS in the normal operation mode.
In flash memory programming mode, connect this pin to the flash programmer.
