CCS/BOOST-DRV8711: STEPPER MOTORS

Hi, 

I am working with DRV8711, NEMA17, and NEMA23 steppers using Delfino79D controller, my interrupt function used to move both two motors takes about 300 microsecond and when i set the interrupt period to that time, motor s responce will be as following:

1- Nema17 stepper will hold at high speed which reaches at [FULL STEPPING] mode.

2- Nema23 stepper will hold even if interrupt period increased from 300 up to 1000 microsecond.

 I ask if this problem related to the motors time constant or to spi command time as i use it inside the interrupt function to change in micro stepping mode and torque register value or related to what !
