Hi experts,
In PBIST negative test in sdl/test/sdl_pbist_test, STR register is written twice
/*TODO: Run PBIST
*0001 Start / Time Stamp mode restart
*1000 Step / Step for emulation mode*/
pPBISTRegs->STR = ((uint32_t)0x00000009u);
/* Start PBIST */
pPBISTRegs->STR = ((uint32_t)0x00000001u);
and describes in TRM,

What do these bits mean and why does bit0 write twice?
Any reply are appreciated.
Thanks,
Shukai
