Hello,
in function CC3220SF_LAUNCHXL_initGeneral() there is a function call to PRCMCC3200MCUInit() but i don't fully understand what happens there.
//
// DIG DCDC VOUT trim settings based on PROCESS INDICATOR
//
if(((HWREG(0x4402DC78) >> 22) & 0xF) == 0xE)
{
HWREG(0x4402F0B0) = ((HWREG(0x4402F0B0) & ~(0x00FC0000))|(0x32 << 18));
}
else
{
HWREG(0x4402F0B0) = ((HWREG(0x4402F0B0) & ~(0x00FC0000))|(0x29 << 18));
}
//
// Enable SOFT RESTART in case of DIG DCDC collapse
//
HWREG(0x4402FC74) &= ~(0x10000000);
Especially the line HWREG(0x4402FC74) &= ~(0x10000000); confuses me a little bit what is the meaning of SOFT RESTART in case of DIG DCDC collapse what will happen here ?
In swru465.pdf i cannot find exactly the registers which will be handled here. Can somebody give me more information about this ?
