1: Stop
EXSYNC
Setting of PLL unused demodulation (external synchronization)
0: PLL used normal operation (initial value)
1: PLL unused external synchronization operation (supply 256fs clock to TMCK)
AMPOPR [1:0]
Oscillation amplifier operation setting

01: Permanent continuous operation
10: Reserved
11: Stop
• _{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 is unlocked.
• _{If the permanent continuous operation is set with AMPOPR[1:0] while the PLL is locked, RERR goes to into the error}
status once. It is possible to set the operation with maintaining the RERR status, if a setting with which even a
changed fs is not regarded as an error due to the PLL status is made with FSERR.
• _{When an automatic stop mode of the oscillation amplifier is set with AMPOPR[1:0], and if the input fs changes within}
the PLL capture range and no lock error occurs, fs is not calculated with the oscillation amplifier stopped. For this
reason, the input data fs and the fs calculation result may not be identical. However, if the channel status fs
information is rewritten in line with input data changes, this information is reflected to the error flag and fs calculation
of the input data is carried out. Since the fs calculation is always done when the oscillation amplifier is set to the
permanent continuous operation mode, fs changes are always reflected to the error flag.
