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.
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.
