AST2600 HPLL calculate formula [SCU200]
HPLL Numerator(M): have fixed value depend on SCU strap.
M = SCU500[10] ? 0x5F : SCU500[8] ? 0xBF : SCU200[12:0]

if SCU500[10] = 1, M=0x5F.
else if SCU500[10]=0 & SCU500[8]=1, M=0xBF.
others (SCU510[10]=0 and SCU510[8]=0)
depend on SCU200[12:0] (default 0x8F) register setting.

HPLL Denumerator (N) =  SCU200[18:13] (default 0x2)
HPLL Divider (P)         =      SCU200[22:19] (default 0x0)
