unsigned mdec_new (unsigned msel) {
       unsigned x=0x4000, im;
       switch (msel) {
                 case 0: return 0xFFFFFFFF;
                 case 1: return 0x18003;
                 case 2: return 0x10003;
                 default:
                        for (im = msel; im <= PLL0_MSEL_MAX; im++)
                                         x = ((x ^ x>>1) & 1) << 14 | x>>1 & 0xFFFF;
                        return x;
}       }

Remark:

The values for SELP, SELI, and SELR are generated by the encoding block and

need not be programmed explicitly.

13.6.4.4 PLL0AUDIO NP-divider register

Remark:

The PLL NP-divider register does not use the direct binary representations of N

and P directly. Instead, it uses encoded versions NDEC and PDEC of N = nsel and P =
psel respectively.

•

The valid range for N = nsel is from 1 to 2^8. This value is encoded into a 10-bit NDEC
value. The relationship can be expressed through the following code snippet:

#define PLL0_NSEL_MAX (1<<8)
/* pre-divider: compute ndec from nsel */
unsigned ndec_new (unsigned nsel) {
       unsigned x=0x80, in;
       switch (nsel) {
                 case 0: return 0xFFFFFFFF;
                 case 1: return 0x302;
                 case 2: return 0x202;
                 default:for (in = nsel; in <= PLL0_NSEL_MAX; in++)
                                         x = ((x ^ x>>2 ^ x>>3 ^ x>>4) & 1) << 7 | x>>1 & 0xFF;
                                  return x;
}       }

•

The valid range for P = psel is from 1 to 2^5. This value is encoded into a 7-bit PDEC
value. The relationship can be expressed through the following code snippet:

#define PLL0_PSEL_MAX (1<<5)
/* post-divider: compute pdec from psel */
unsigned pdec_new (unsigned psel) {
unsigned x=0x10, ip;
