(Note1)
When each ground pin ( DVSS, AVSS, PVSS1, PVSS2 ) is at 0 V ( voltage reference ).
In this specification, PVDD1 and PVDD2 are expressed as PVDD ( as a general comment ) hereafter.
Similarly, DVDD, XVDD are expressed as DVCC, and AVDD and AVDD as AVDD.
Each ground pin is always kept to the same reference voltage, 0 V with no potential difference.

Exclude Power supply pin.

Note 1) excluding interface power supply. 1.8 V power supply can be supplied only to the interface part.
Note 2) interface power supplies PVDD1, PVDD2 can be used as 3 V or 1.8 V power supply interface
each.
But when the 1.8 V interface is not selected, same potential as DVCC is used as interface power supply.
(Example PVDD1 = 1.8 V, PVDD2 = DVDD = 3 V)
Note 3) as described at the note in item ( 1 ) above, PVDD1 and PVDD2 are expressed as PVDD in this
table. Similarly, DVDD and XVDD are expressed as DVCC, and AVDD and AVDD as AVDD.
