OPERATING MODES
PSM0 (NORMAL MODE)
In PSM0, or normal operating mode, V
V
by V
default clock frequency, f
power-on reset or software reset, is 1.024 MHz.
PSM1 (BATTERY MODE)
In PSM1, or battery mode, V
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 V
automatically restarts, and the switch to the V
occurs, when the V
the MODE1 register (Address 0x0B) is cleared (see Table 33). The
default f
software reset, is 1.024 MHz.
PSM2 (SLEEP MODE)
PSM2 is a low power consumption sleep mode for use in battery
operation. In this mode, V
2.5 V digital and analog circuitry powered through V
is disabled, including the MCU core, resulting in the following:

The 3.3 V peripherals (temperature ADC
and LCD) are active in PSM2. 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 peripherals and their PSM2 configuration).
The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569 remain in PSM2 until an event occurs to wake them up.
In PSM2 mode, the ADE7116/ADE7156/ADE7166/ADE7169/
ADE7566/ADE7569 provide four scratch pad RAM SFRs that
are maintained during this mode. These SFRs can be used
to save data from PSM0 or PSM1 mode when entering PSM2
mode (see Table 22 to Table 25).
In PSM2, the ADE7116/ADE7156/ADE7166/ADE7169/
ADE7566/ADE7569 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.
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 ADE7116/ADE7156/ADE7166/ADE7169/
ADE7566/ADE7569 exit PSM2.
