■
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
PLL is powered-up (PMPLL bit = “0” → “1”) or sampling frequency changes.
1) Setting of PLL Mode
Note 28. Please see
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
Note 29. In case of PLL3-0 bits = “1001”
