When PMPLL bit is “1”, a fully integrated analog phase locked loop (PLL) generates a clock that is selected by the
PLL3-0 and FS3-0 bits. The PLL lock time is shown in Table 4, whenever the AK5702 is supplied to a stable clocks after
PLL is powered-up (PMPLL bit = “0” → “1”) or sampling frequency changes.
1) Setting of PLL Mode
Note 29. See Table 5 regarding the difference between PLL3-0 bits = “0110”(Mode 6) and “1001”(Mode 9).
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 30. In case of PLL3-0 bits = “1001”
