Power supply voltages are values where each ground pin ( DVSS = AVSS = PVSS ) is at 0 V
( voltage reference ).All power supply ground pins DVSS, AVSS and PVSS should be at same potential.
When to connect to Data bus such digital output pins as CLKO, D[7:0], FIELD, HD, VD, NSIG, DVALID,
Data bus operating voltage must be within the input pin voltage range as described above.

Digital output pins refer to CLKO, D[7:0], FIELD, HD/HV, VD/VAF, NSIG and DVALID pin outputs in general
term.
Digital inputs which are specified by VIH1, VIH2, VIL1 and VIL2 refer to OE, PDN, RSTN,SCL and SDA pin
inputs in general term.
Digital input which is specified by VIH3 and VIL3 means XTI input.
SDA pin output is not included in digital output pin unless otherwise noted.
