MMA8652 : Transient interrupt threshold value

koichisakagami — Tue, 03 Feb 2026 22:20:18 GMT

Dear community,

I consider the Transient interrupt threshold value.

In the case of setting to register value as follows,
when does the Transient interrupt occur ?

0x1F:TRANSIENT_THS Register THS[6:0] to 000_0000b.
0x1D:TRANSIENT_CFG Register HPF_BYP to 1.

Which is the Transient interrupt trigger point value ,
" greater than or equal to ZERO G " or " greater than ZERO G " ?

Best Regards,
Koichi Sakagami

Dear Koichi-san,

What is the use of such settings? The interrupt would be generated whenever the acceleration is higher than 0g.

Best regards,

Tomas

Dear Tomas san,
Thank you for your reply.

> What is the use of such settings?
I would like to detect a less than 0.063g transient.

Dear Koichi-san,

The minimum threshold resolution is 0.063g (TRANSIENT_THS = 0x01). None of our accelerometers offer higher resolution.

Best regards,

Tomas
