Note
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 1.

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 21H.
