Need to know what this means?

[Animesh Hazarika]

So I have a Acer Nitro 5 An515-42 ,The CPU  (Ryzen 5 2500U )would throttle down to base clock (2GHz) once it reached  75*c and boost back again once the temps dropped to around 65*c . So I dumped the DSDT.aml  file using Clover . In the DSDT file i found a line THTR 1, I changed it to TTHR 0 . now it no longer throttles but the inbuilt fan controlling software Nitro Sense is now reporting weird Temperatures . So I want to know what TTHR means ??  

and what this condition below  means?

            Method (ATHR, 1, NotSerialized)
            {
                If ((Arg0 == Zero))
                {
                    Return (0xFF)
                }
                ElseIf ((Arg0 == One))
                {
                    Return (\_PR.C000.PPCV) /* External reference */
                }
                ElseIf ((Arg0 == 0x02))
                {
                    Return (TTHR)
                }
                Else
                {
                    Return (0xFF)
                }
            }
