DRV8301-69M-KIT: BLDC loop

Part Number: DRV8301-69M-KIT

Hi TI team,

We are using BLDC mode to run the motor. But we noticed there is 20 count (gHall_Bldc_Cnt ) when it enters from FASTtoBLDC and BLDCto FAST.  How this value is defined to 20. Do we need to fine tune gHall_Bldc_Cnt value  or this value is  constant throughout the system. 

if(_IQabs(speed_est_pu) < gHall_speed_FastToBldc_low_pu) // FAST to Hall
{
if(gHall_Flag_EnableBldc == false)
{
if(gHall_Bldc_Cnt > 20)
{
gHall_Flag_EnableBldc = true;
gHall_Bldc_Cnt = 0;

if(gHall_Flag_CurrentCtrl == true) // Torque Control Mode
{

Thanks
