Data Sheet
External Voltage ADC in PSM1 and PSM2 Modes
An external voltage conversion is initiated only by certain actions
that depend on the operating mode of the ADE5166/ADE5169/
ADE5166/ADE5169/ADE5566/ADE5569
External Voltage ADC Interrupt
The external voltage ADC can generate an ADC interrupt when
at least one of the following conditions occurs:
ADE5566/ADE5569.
?
The difference between the new external voltage ADC
?
?
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 VDCIN_ADC_GO in the start
ADC measurement SFR (ADCGO, Address 0xD8[2]).
?
value and the last external voltage ADC value generating
an ADC interrupt is larger than the value set in the
VDCIN_DIFF bits in the temperature and supply delta
SFR (DIFFPROG, Address 0xF3[2:0]).
The external voltage ADC conversion, initiated by setting
the VDCIN_ADC_GO bit in the start ADC measurement
SFR (ADCGO, Address 0xD8[2]), finishes.
?
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.
When the ADC interrupt occurs, a new value is available in the
V DCIN ADC value SFR (VDCINADC, Address 0xEF). Note that
there is no flag associated with this interrupt.
The external voltage ADC in the V DCIN ADC value SFR
(VDCINADC, Address 0xEF) is updated with a new value
only when an external voltage ADC interrupt occurs.
