Use it when VREF is applied by dividing resistive voltage of VCC.
(Refer to the following section of ‘SVF pin’.)
When VCC is used as the switch for high level or as the
connecting point for pulled up resistor, short-circuit
SR3. In this case, do not apply voltage to VDD pin.
When VDD (external power supply) is used as the switch
for high level or as the connecting point for pulled up
resistor, apply 3.3 V or 5 V to VDD pin. In this case, do not
short-circuit SR3.
When VREFA and VREFB are applied as
common power supply, short-circuit
SR5. In this case, apply the voltage to
only one of them, VREFA or VREFB.
