If the PLL is stopped with PLLOPR while the PLL is locked, the output clocks are all muted and this muted status
continues even if the PLL becomes unlocked.
If the permanent continuous operation setting is performed with AMPOPR0,1 while the PLL is locked, RERR goes
to into error status once. However, the RERR status can be set to be maintained if a setting so that no error is output
according to the PLL status even if the sampling frequency changes with FSERR is performed.
When the oscillation amplifier automatic stop mode is set with AMPOPR0,1, if the input sampling frequency
changes within the capture range of the PLL and no lock error occurs, sampling frequency calculation is not
performed in the oscillation amplifier stop status, so that the input data sampling frequency and the fs calculation
result may differ. However, if the channel status sampling frequency information is rewritten together with input
data changes, this information is reflected to the error flag and fs calculation of the input data is performed. Since
the oscillation amplifier permanent continuous operation setting is performed by permanent fs calculation, sampling
frequency changes are always reflected to the error flag.
