Preliminary Technical Data
PSM2 Settings
This panel gives access to LPOILVL[7:0] register that is used to
access PSM2 low power mode (see Figure 29). The user can
manipulate its LPOIL[2:0] and LPLINE[4:0] bits. The value
shown into LPOILVL[7:0] register is composed from these bits
and then visualized. Writing a value to LPOILVL[7:0] register
window directly does not have any consequence.
Enter PSM1 Mode
When “Enter PSM1 mode” is selected, the microcontroller
manipulates PM0 and PM1 pins of ADE7878 to switch it into
PSM1 reduced power mode. Then the submenu only allows
accessing the Mean Absolute Value Current function because
this is the only ADE7878 functionality in this reduced power
mode (see Figure 30).

Mean Absolute Value Current in PSM1 Mode
(see Mean Absolute Value Current Chapter for details). The
only difference is that ADE7878 status does not show
CHECKSUM[31:0] register because it is not available in PSM1
mode ( Figure 31)
Enter PSM2 Mode
When “Enter PSM2 mode” is selected, the microcontroller
manipulates PM0 and PM1 pins of ADE7878 to switch it into
PSM2 low power mode. Then the submenu only allows
accessing the Phase Current Monitoring function because this is
the only ADE7878 functionality in this low power mode.
This panel is very similar to the panel accessible in PSM0 mode
