Control MCU Family. The interface to the pyroelectric sensor is via the dedicated input ANA2
(pin 5). The status LED is driven by pin 6 which is normally configured as a GPIO by the
application to control the state of the LED. Pin 2 is used as the debug input to the chip, but can
be used for other functions as required. Pin 4 is set up for the Reset function, but may also be
used for other functions as the application requires. Pull-up resistors (10K) are provided on the
Debug and Reset signals as required for the Debug interface. The signals on pins 3 and 7 can
be used as needed. The power supply design is left to the application needs.
In Dual Pyro mode, the second Pyroelectric sensor is connected to Pin 3 (ANA3). All other
connections remain the same.
