Bit Symbol Description
14 to 11 - address bits
10 to 0 SO[10:0] 11-bit digital-to-analog converter for adjusting the stereo decoder clock
[1] The frequency is decreased when increasing the content of this register.
Integrated FM stereo radio IC for host processor tuning
Description
address bits
selects an internal circuit as output for measurement purpose;
see Table 10
mutes the stereo PLL when set to logic 1; this bit should be
set during calibration of the stereo decoder clock and should be
cleared during normal operation
mutes the demodulator PLL when set to logic 1; this bit
should be set during calibration of the IF frequency and should
be cleared during normal operation
turns off the stereo integrator loop when set to logic 0
enables measurement when set to logic 0
mutes the audio when set to logic 1
enables the FM circuitry when set to logic 1
reserved for AM circuitry; should be written to logic 0
