OPERATING MODES
PSM0 (NORMAL MODE)
In PSM0 mode, or normal operating mode, VSWOUT is connected to
VDD. All of the analog circuitry and digital circuitry powered by
VINTD and VINTA are enabled by default. In normal mode, the
default clock frequency, fCORE, which is established during a
power-on reset or software reset, is 1.024 MHz.
PSM1 (BATTERY MODE)
In PSM1 mode, or battery mode, VSWOUT is connected to VBAT.
In this operating mode, the 8052 core and all of the digital circuitry
are enabled by default. The analog circuitry for the ADE energy
metering DSP powered by VINTA is disabled. This analog circuitry
automatically restarts, and the switch to the VDD power supply
occurs when the VDD supply is greater than 2.75 V and the
PWRDN bit in the MODE1 register (Address 0x0B) is cleared
(see Table 33). The default fCORE for PSM1, established during
a power-on reset or software reset, is 1.024 MHz.
PSM2 (SLEEP MODE)
PSM2 mode is a low power consumption sleep mode for use
in battery operation. In this mode, VSWOUT is connected to VBAT.
All of the 2.5 V digital and analog circuitry powered through VINTA
and VINTD is disabled, including the MCU core, resulting in the
following:
The RAM in the MCU is no longer valid.
The program counter for the 8052, also held in volatile
memory, becomes invalid when the 2.5 V supply is shut
down. Therefore, the program does not resume from where
it left off but always starts from the power-on reset vector
when the ADE5166/ADE5169/ADE5566/ADE5569 exit
PSM2 mode.
The 3.3 V peripherals (temperature ADC, VDCINADC, RTC, and
LCD) are active in PSM2 mode. They can be enabled or disabled
to reduce power consumption and are configured for PSM2
operation when the MCU core is active (see Table 29 for more
information about the individual peripherals and their PSM2
configuration). The ADE5166/ADE5169/ADE5566/ADE5569
remain in PSM2 mode until an event occurs to wake them up.
In PSM2 mode, the ADE5166/ADE5169/ADE5566/ADE5569
provide four scratch pad RAM SFRs that are maintained during
this mode. These SFRs can be used to save data from the PSM0
or PSM1 mode when entering PSM2 mode (see Table 22 to
Table 25).
In PSM2 mode, the ADE5166/ADE5169/ADE5566/ADE5569
maintain some SFRs (see Table 28). The SFRs that are not listed
in this table should be restored when the part enters PSM0 or
PSM1 mode from PSM2 mode.
