Is there a way to overcome "pausing" during DMA Circular transfer?

[ambrose]

Hello I am using the STM32F334 for Lighting and I have had to use the DMA to transfer duty cycle data to the PWM duty register. The DMA is set up in circular mode and there is no interrupt. The priority it set to High. But i notice this pauses between the packets. I would have expected it to have no pauses. Please how can I get rid of this? Please see the image of actual light intensity. Hope to hear from you. thanks
