Description
Enables a PSM interrupt when the Power Supply Restored flag is set.
If set, the ADE interrupt status registers MIRQSTH/M/L registers will be read with reset.
Enables a PSM interrupt when the voltage sag flag (FSAG) is set.
This bit must be kept cleared for proper operation
Enables a PSM interrupt when the V
Enables a PSM interrupt when the V
Enables a PSM interrupt when the Battery Switchover flag (FBSO) is set.
Enables a PSM interrupt when the V
Description
Value can be written/read in this register. This value will be maintained in all the power
saving modes of the ADE7169F16

PSM2 mode.
This bit should be kept to zero
RXPROG [1:0]
If set, indicates that VDD power supply is ok for operation
If set, indicates that PLL is not locked
If set, Internal voltage reference enabled in PSM2 mode. This bit should be set if LCD On in
These bits must be kept to 0 for proper operation
Control bits for Battery Switchover.
BATPRG [1:0]
Indicates the power supply that is connected internally to V
Controls the function of the P1.0/RX pin.
If set, indicates that a RX Edge event triggered wakeup from PSM2
