Please someone help me in the following problems.
How many configurable/ non-configurable interrupts are there in the IMU?
How can the interrupts be configured?(If configurable)
Are there any interrupts for data ready and enable activity detection?
Are there interrupts for machine learning core recognition?
Are there an interrupt for double tap detection?
Can the mlc or enable activity detection and double tap detection configured in one interrupt pin using a multiplexer
so that the other interrupt pin can be allocated to the data ready interrupt?
Thanks In Advance!!
Best Regards,
Nipun D.

Hi Sir:
Do you have BHI260AB or BHA260AB datasheet?
Please see 4.3.1 Host interrupt and 12.1.8 Host Interrupt Control(0x07) to know BHY2 interrupt.
Please see 4.1 Connect Diagram and 4.3 Physical Primary Host Interface, you can know only one interrupt pin, HIRQ, to conncet to HOST CPU.
When you want to achieve a feature, you should enable the corresponding virtual sensor, but they don't have the individual interrupt pin. Via HIRQ and host interrupt connection, host is notified to read fifo data and parse these data to konw the related status and sensor data.
Read the reference code of BHI2 and datasheet, more details are got.
