Hi,

this seems to be correct. FRET reset value is 0xF as the RM indicates, and DRET can be changed by sBAF, see Figure 132 in the RM.

BR, Petr

Hi,Petr

When I was testing the reset function, after 8 resets, the chip stopped working.

After investigation, it was found that the chip may have entered recovery mode.

When I assign the DRET/FRET registers, the chip still works fine after 8 resets after .

Power_Ip_pxMC_RGM->FRET = 15;
Power_Ip_pxMC_RGM->DRET = 0;

My understanding is that I didn't turn off recovery mode,

I just re-assigned DRET/FRET, why recovery mode doesn't work

BR,

Luhaiou
