Data Sheet
3.3 V PERIPHERALS AND WAKE-UP EVENTS
Some of the 3.3 V peripherals are capable of waking the ADE5166/
ADE5169/ADE5566/ADE5569 from PSM2 mode. The events that
can cause the ADE5166/ADE5169/ADE5566/ADE5569 to wake
up from PSM2 mode are listed in the wake-up event column in
Table 29. 3.3 V Peripheral s and Wake-Up Events
ADE5166/ADE5169/ADE5566/ADE5569
Table 29. The interrupt flag associated with these events must
be cleared prior to executing instructions that put the ADE5166/
ADE5169/ADE5566/ADE5569 in PSM2 mode after wake-up.

Comments
The temperature ADC can wake up the ADE5166/ADE5169/
ADE5566/ADE5569. A pending interrupt is generated according
to the description in the Temperature Measurement section.
This wake-up event can be disabled by disabling temperature
measurements in the temperature and supply delta SFR
(DIFFPROG, Address 0xF3) in PSM2 mode. The temperature
interrupt needs to be serviced and acknowledged prior to
entering PSM2 mode.
V DCIN ADC
ΔV
Maskable
FVADC
(IPSMF[3])
IPSM
The V DCIN measurement can wake up the ADE5166/ADE5169/
ADE5566/ADE5569. The FVADC flag, Bit 3 of the power manage-
ment interrupt flag SFR (IPSMF, Address 0xF8), is set according to
the description in the External Voltage Measurement section.
This wake-up event can be disabled by clearing the EVADC bit,
Bit 3 in the power management interrupt enable SFR (IPSME,
Address 0xEC); see Table 21. The FVADC flag needs to be cleared
prior to entering PSM2 mode.
Power Supply
Management
PSR
Nonmaskable
FPSR
(IPSMF[7])
IPSM
The ADE5166/ADE5169/ADE5566/ADE5569 wake up if the power
supply is restored (if V SWOUT switches to be connected to V DD ). The
VSWSOURCE flag, Bit 6 of the peripheral configuration SFR (PERIPH,
Address 0xF4), is set to indicate that V SWOUT is connected to V DD .
RTC
Interval
Maskable
ITFLAG
(TIMECON[2])
IRTC
The ADE5166/ADE5169/ADE5566/ADE5569 wake up after the
programmable time interval has elapsed. The RTC interrupt needs
to be serviced and acknowledged prior to entering PSM2 mode.
Alarm
Maskable
ALFLAG
(TIMECON[6])
IRTC
An alarm can be set to wake the ADE5166/ADE5169/ADE5566/
ADE5569 after the desired amount of time. The RTC alarm is
enabled by setting the ALxxx_EN bits in the RTC Configuration 2
SFR (TIMECON2, Address 0xA2). The RTC interrupt needs to be
serviced and acknowledged prior to entering PSM2 mode.
I/O Ports 1
INT0
INT0PRG = 1
(INTPR[0])
N/A
IE0
The edge of the interrupt is selected by the IT0 bit, Bit 0 in the
TCON SFR (TCON, Address 0x88). The IE0 flag, Bit 1 in the TCON
SFR, is not affected. The Interrupt 0 interrupt needs to be serviced
and acknowledged prior to entering PSM2 mode.
INT1
INT1PRG = 11x
(INTPR[3:1])
N/A
IE1
The edge of the interrupt is selected by the IT1 bit, Bit 2 in the
TCON SFR (TCON, Address 0x88). The IE1 flag, Bit 3 in the TCON
SFR, is not affected. The Interrupt 1 interrupt needs to be
serviced and acknowledged prior to entering PSM2 mode.
Rx2 edge
RXPROG = 11
(PERIPH[1:0])
RX2FLAG
(PERIPH[7])
N/A
An Rx edge event occurs if a rising or falling edge is detected
on the RxD2 line. The UART2 RxD flag needs to be cleared prior
to entering PSM2 mode.

All I/O pins are treated as inputs. The weak pull-up on each I/O pin can be disabled individually in the Port 0 weak pull-up enable SFR (PINMAP0, Address 0xB2), Port 1
weak pull-up enable SFR (PINMAP1, Address 0xB3), and Port 2 weak pull-up enable SFR (PINMAP2, Address 0xB4) to decrease current consumption. The interrupts can
be enabled or disabled.
