When PMPLL bit is “1”, a fully integrated analog phase locked loop (PLL) generates a clock that is selected by the
PLL4-0 and FS3-0 bits (Table 4, Table 5, Table 6). The PLL lock time is shown in Table 4, whenever the AK4371 is
supplied to a stable clocks after PLL is powered-up (PMPLL bit = “0” → “1”) or sampling frequency changes.
1) Setting of PLL Mode
2) Setting of sampling frequency in PLL Mode
When PLL reference clock input is MCKI pin, the sampling frequency is selected by FS3-0 bits as defined in Table 5.

Note 32. Refer to Table5 about Type1-4
Note 33 : Clock jitter is lower in Mode10 ~13 than Mode5, 7, 8 and 9, respectively.
Note 34. Modes 14~16 are available at Slave Mode only.
