This pin is used to enable serial download mode when pulled low through a resistor on power-up or
reset. On reset this pin will momentarily become an input and the status of the pin is sampled. If there is
no pulldown resistor in place, the pin will go momentarilly high and then user code will execute. If a
pull-down resistor is in place, the embedded serial download/debug kernel will execute and this pin
remains low during internal program execution. This pin can also be used as a general purpose output.
Digital Input for Battery control. This logic input connects V
High or Low respectively. When left open, the connection between V
internally / External Interrupt input / General-purpose digital I/O
A crystal can be connected across this pin andXTAL1 as described above to provide a clock source for
the ADE7169F16.The XTAL2 pin can drive one CMOS load when an external clock is supplied at XTAL1 or
by the gate oscillator circuit.
An external clock can be provided at this logic input. Alternatively, a parallel resonant AT crystal can be
connected across XTAL1 and XTAL2 to provide a clock source for the ADE7169F16.The clock frequency
for specified operation is 32.768 kHz.
General-purpose digital I/O / Interrupt input
Analog Inputs for Voltage Channel. These inputs are fully differential voltage inputs with a maximum
differential level of ±500mV for specified operation. This channel also has an internal PGA.
