Clock source; RDA TA output setting:
When the oscillation amplifier is set to permanent continuous operation using AMPOPR[0:1] or if
changes are set not to be reflected to the error flag using FSERR, OCKSEL and RCKSEL can switch
the clock source while maintaining the RERR status. However, RERR outputs an error during
switching if none of these settings are performed.
A clock synchronized to the SDIN input data is selected to input data to SDIN.
The XIN source can be switched while maintaining the PLL locked status. However, since clock and
data output switching can be set individually for each, it is recommended to select mute or SDIN data
for the output data during XIN source switching.
If AMPOPR[0:1] is set to automatically stop the oscillation amplifier during PLL locked, XIN source
switching from the PLL locked status is executed only after the resonator is oscillating stably. Output
data switching is also done at this time according to XIN source switching.
