TMS570LS3137: TMS570LS3137 HALCOGEN Code loops wait time

Hello,

We are using HALCOGEN generated code for TMS570LS3137 controller. in the generated code, we have few while loops which checks for the status bits. Below are few of the loops which i am talking about.

sample1: 

file name : sys_startup.c

function name: afterSTC()

Code: 

while ((mibspiREG1->FLG & 0x01000000U) == 0x01000000U)
{
}

sample2: 

file name : sys_selftest.c

function name: ccmSelfCheck()

Code: 

while ((CCMSR & 0x100U) != 0x100U)
{
}

There are few more places where these kind of while loops are generated. i would like to know the time elapses in these while loops. Is there any document which captures these time elapses?

Thanks,

Kalyan
