Notes
1)The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono
intercarrier FM demodulator/QSS IF amplifier and East-West output or not) and on some
software control bits. The valid combinations are given in table 2.
2)The vertical guard function can be controlled via pin 49 or pin 50. The selection is made by
means of the IVG bit in subaddress 2BH.

Notes
1) When additional (external) selectivity is required for EM-Pll system pin 32 can be used
used as sound IF input. This function is selected by means of SIF bit in subaddress 28J.
2) The reference output signal is only available for the CMB1/CMBO setting of 0/1. For
the other settings of this pin is a switch output.
