CC1312R7: Problem to received messages with preamConf.preamMode = 0

Hi,

We work to move our system to CC1312R7 and have problem to receiving messages with first preamble bit 0 ".preamConf.preamMode = 0"

In the past when we had this problem in CC1310 device TI recommended to define :
HW_REG_OVERRIDE(0x52AC,0x130C),

HW_REG_OVERRIDE(0x5104, 0x2F2F)

1. Where I can fined the explanation on this overrides ?

2. Is this override and this values are relevant to CC1312R7 ?
3. What your recommendation to solve this issue

Thanks in advance
