• Select the demodulated data and the SDIN input data with RDTSEL and RDTSTA, and mute processing can be
• Moreover, GPIO0 input data can be selected with EXTSEL. Also, GPIO0 can be subject to mute processing with
10.3.5 Calculation of input data sampling frequency (MOUT)
• The input data sampling frequency is calculated using the XIN clock.
• In the mode where the oscillation amplifier automatically stops according to the lock status of the PLL, the input data
• If the oscillation amplifier is in a continuous operation mode, calculation is repeated constantly. Even if sampling
• The calculation results can be readout via MOUT pin or with the microcontroller interface. Since the MOUT pin is
performed with RDTMUT.

sampling frequency is calculated during the RERR error period and completed when the oscillation amplifier stops
with holding the value. Therefore, the value remains unchanged until the PLL becomes unlocked.
changes within the PLL capture range for input data whose channel status sampling information does not change, the
calculation results that follow the input data can be read.
also used to generate the emphasis information, set the contents of the MOUT pin output by MOSEL. The fs
calculation output to the MOUT pin is limited. The FSSEL[1:0] sets the contents of the MOUT pin output.
