I'm applying PWM to on high side gate speed is not getting controlled, is there any way to control speed?

I've done all required coonection motor is running but speed isn't getting control precisely base on duty cycle , during 50-100 duty cycle hall frequency is almost constant
I'm using driver in 6x mode(sensored) , mode pin is to GND, & 3 PWM i've given to high side gate INHx , do i have to introduce dead time in between pwm?
& if i'm giving 3 pwm to high side only , which mode do i have to select 3x or 6x?
You should use 3x PWM mode if you're using 3 high side PWMs. Set the MODE pin to GND using a 47kohm resistor. This produces synchronous PWM gate drive outputs on GHx/GLx. You cannot insert dead time from the MCU in this mode, the dead time will be fixed to 100ns.
