CCS/BOOSTXL-DRV8301: How to read low side current if high side switches are on with duty cycle of 100% ?

Part Number: BOOSTXL-DRV8301

Tool/software: Code Composer Studio

Hello,

In order to read the low side currents, the low side switch should be on and this is how the currents are read in Insta-spin FOC. My question is that what if two high side switches are completely "ON" during the sampling time and one of them is completely "OFF" during the sampling time. In this case, I can only read one current correctly, right? Is there a way to read the other currents also, or maybe calculate them based on the switching states?

I am asking this question because I want to implement direct torque control (DTC) algorithm and in this algorithm, switches are on/off completely during the sampling time.

Regards,
