Energy metering IC
9.1 BOD static characteristics
[1]
Interrupt levels are selected by writing the level value to the BOD control register BODCTRL, see EM773
user manual.
9.2 Power consumption
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions (see EM773 user manual):
• Configure all pins as GPIO with pull-up resistor disabled in the IOCONFIG block.
• Configure GPIO pins as outputs using the GPIOnDIR registers.
• Write 0 to all GPIOnDATA registers to drive the outputs LOW.
