CC2652R7: CC2652R7 - Clock_getTicks() unit clarification

Hi Team

We are trying to calculate the duration of our process using the Clock_getTicks call. I am attaching my code snippet below,

Left_CurrentTickStart = Clock_getTicks();

Left_CurrentTickEnd = Clock_getTicks();

Left_ProcessDuration = (Left_CurrentTickEnd - Left_CurrentTickStart);

Left_ProcessDuration is printing as 3000 ticks 

We wanted to know what will be the unit of  Left_ProcessDuration 

Below is our MCU clock configuration in our sysconfig
