Table 16. PDN Bit Operation
PDN
VALUE
DESCRIPTION
0
Internal reference is powered at all times
1
Internal reference is powered down between conversions. (default)
Note that the PDN bit, in concert with the INT bit, creates a few possibilities for reference behavior. These are detailed
in Table 17.

REFERENCE BEHAVIOR
0
External reference used, internal reference powered down.
0
1
External reference used, internal reference powered down.
1
0
Internal reference used, always powered up
1
Internal reference used, powers up during conversions and then powers down.
Bit 0 — RFV
Reference Voltage control. This bit selects the internal reference voltage, either 1.2 V or 2.5 V. The default value is 1.2
V. This bit is the same whether reading or writing.
