This section describes the required external hardware connection for the ZMOTION MCU
Series. See
matic diagrams showing these connections.
Pins are automatically configured to their required function when the PIR Engine is initial-
ized via the EPIR_INIT macro. The device can be operated in Single Pyro Mode when
supporting one pyroelectric sensor or in Dual Pyro Mode when supporting two pyroelec-
tric sensors. Both of these modes can be operated in Normal or Low Scan Rate modes.
Depending on the application, there can be up to four connection requirements supporting
these modes: one for each of two PIR sensors, one for the ADC and one for the White
Light Detection and Status LED. A description of each of these elements follows in this
section. For a broader description of the White Light Detection component, see the

The signal from the PIR sensor is connected directly to the ANA2 input of the ADC. The
ADC is configured for differential buffered mode by Zilog’s PIR technology. The sensor
signal should be connected directly to the ADC input with no additional signal condition-
ing circuitry unless specified by the pyroelectric sensor manufacturer.

In Dual Pyro Mode, the ADC is still used in differential buffered mode (i.e., as is true for
Single Pyro Mode). The signal from the second PIR sensor is connected to ANA3. The
