Dear user, it depends on how you configure the int pin electrical behavior, by default the INT1&INT2 pins are disabled, so you need to properly enable the output and active level, and the push-pull/open drain behavior. normally, once: 1. the acc_en in reg0x7D is enabled, 2. fifo_acc_en is enabled in reg0x48, 3. fwm/ffull is mappeded in reg0x58, 4. configure INT1/INT2 pin output in reg0x53&0x54 the corresponding interrupt will be enabled, you should see the interrupt signaled out. if this issue still there, you'd better dump all the register map and share to us. better to check the waveform of initialization and interrupt behavior(spi/i2c + INT1) with logic analysor.
