DRV8323: Question about the automatic trim routine

Hi,

I'd like to know about the description in DRV8323 D/S as follows,

P45 8.3.4.3 Auto Offset Calibration

「The automatic trim routine requires 100 µs to complete after the calibration is enabled.」

Does it mean that 100us will be required for each internal AMP? in short, It'll need 300us in total?

or need 100us for 3 AMPs?

Thanks,
