Differential or single-ended Line Current Sense Inputs:
These pins are voltage inputs to the internal A/D
converter. Typically, they are connected to the outputs
of current sensors. Unused pins must be tied to
V3P3A.
Pins IBP-IBN may be configured for communication with
the remote sensor interface (71M6x01). When RMT_E =
1 (I/O RAM 0x2709[3]), the IBP-IBN pins become
balanced differential pair. If unused, RMT_E must be
zero and IBP-IBN must tied to V3P3A.

Line Voltage Sense Inputs: These pins are voltage

Crystal Inputs: A 32 kHz crystal should be connected
across these pins. Typically, a 15 pF capacitor is also
connected from XIN to GNDA and a
10 pF capacitor is connected from XOUT to GNDA. It
is important to minimize the capacitance between these
pins. See the crystal manufacturer datasheet for details.
If an external clock is used, a 150 mV (p-p) clock signal
should be applied to XIN, and XOUT should be left
unconnected.
Pin VB only available on 71M6542F.
