External Voltage ADC in PSM0, PSM1, and PSM2 Modes
An external voltage conversion is initiated only by certain actions
that depend on the operating mode of the ADE7156/ADE7166/
ADE7169/ADE7566/ADE7569.
•
•
•
In PSM0 operating mode, the 8052 is active. External
voltage measurements are available in the background
measurement mode and by initiating a single measurement.
In PSM1 operating mode, the 8052 is active and the part is
powered from battery. Single external voltage measurements
can be initiated by setting the VDCIN_ADC_GO bit (Bit 2)
in the start ADC measurement SFR (ADCGO, Address
0xD8). Background external voltage measurements are not
available.
In PSM2 operating mode, the 8052 is not active. External
voltage conversions are available through the background
measurement mode only.

The external voltage ADC in the V
(VDCINADC, Address 0xEF) is updated with a new value only
when an external voltage ADC interrupt occurs.
External Voltage ADC Interrupt
The external voltage ADC can generate an ADC interrupt when
at least one of the following conditions occurs:
•
•
When the ADC interrupt occurs, a new value is available in the
V
there is no flag associated with this interrupt.
DCIN
The difference between the new external voltage ADC
value and the last external voltage ADC value generating
an ADC interrupt is larger than the value set in the
VDCIN_DIFF[2:0] bits in the temperature and supply
delta SFR (DIFFPROG, Address 0xF3).
The external voltage ADC conversion initiated by setting
VDCIN_ADC_GO, finishes.
