DRV8842 VREF pin problem with V3P3OUT * (2K / 3K)

Hi.

We are trying to control 24V 65W DC motor with DRV8842. I can controlling motor with 100kHz PWM and can change direction with EN/PHASE interface but the speed of the motor is not enough. First I've set the current limit inputs to 80% and put the VREF pin ~2.2V with 1K pullup and 2K pulldown but I can't see the 2.2V or near on the VREF. I'm just seeing ~0.25V on VREF. V3P3OUT is actually 3.3V. I've attached circuit and PWM + motor output waveforms in a 7zip file(Please visit the site to view this file).
