Interrupt Pins - Mcube MC3635 Quick Start Manual And Demo

MC3635 3-Axis Accelerometer
R4, R5: If using I2C and I2C pull-up resistors are needed for your application then
install~4.7KΩ resistors into R4 (SCL clock pin) and R5 (SDA data pin) which are not
installed by factory default. In addition, besides soldering resisters on R4/R5, you can add
axial lead 4.7K ohm resistors to the SDA and SCL pin respectively. It will work the same
either way.
NOTE: DO NOT install more than one setup pull-up resistors per I2C bus.

1.4 INTERRUPT PINS

INT - HW interrupt signal pin. It will be driven by the chip 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 toward related
registers).
R6: If using the sensor interrupt signal as open-drain, then install pull-up resistor ~4.7KΩ
into R3 (not installed by default).
