3.2 Voltage distribution
The table shows the required device power supply pins and their function:
Device supply pin
Function
REG0VDD
REG1VDD
Supply for the device internal regulators for the digital
logic.
EVDD
Supply for ports.
BVDD
Supply for ports.
A0VREF
Supply for ports and analog functions of ADC0.
A1VREF
Supply for ports and analog functions of ADC1.
VDDIOF
IO supply voltage for the Mainboard.
 For each of the above voltages, the voltage source can be selected from
Voltage1 (typ. 5.0V) or Voltage2 (typ. 3.3V) by the jumpers JP1-JP6, JP7,
respectively the jumpers JP0, JP9.

Note:
 The RH850/F1KH-D8 device requires a supply voltage of 3.3V on its
REG1VCC pin.
 The RH850/F1KM-S4 device requires the same supply voltage to be set
to REG0VCC and REG1VCC.
