Note
1. When additional (external) selectivity is required for FM-PLL system pin 32 can be used as sound IF input.
This function is selected by means of SIF bit in subaddress 28H.
2.
the reference output signal is only available for the CMB1/CMB0 setting of 0/1. for the other settings this pin is
a switch output(see also 5 table 67).
