1.4 SPI PINS

With an SPI connection, there is always one master device (usually a microcontroller)
which controls the peripheral devices. Typically, there are four wires commonly connected
to all the devices:
Connect the SCS (Slave Chip Select) to the pin on the device that the master can use to
enable and disable SPI cycles.
Connect the SCL (Serial clock) to the pin where the clock pulses synchronize data
transmission generated by the master
Connect SDO to the pin
Output).
Connect SDA to the
Slave Input).

1.5 INTERRUPT PINS

INT - HW interrupt signal pin. This pin will be triggered by the device when data is ready
to read, or a motion event is detected by the accelerometer. (Not currently supported in
the library for the interrupt pin, so please check the datasheet for the I2C commands and
related registers).
R6: If using the sensor interrupt signal as open-drain, then install pull-up resistor ~4.7KΩ
into R6 (not installed by default).
