Table 1
Pin functions for various versions
Note
1. When the AM/FM mode is chosen several pins have a different function. For this reason this mode can be selected only when the adapted
application is used.
2. When in the AM/FM mode the AM bit is activated a capacitor with a value of about 2.2
µF has to be switched externally in parallel with the sound
PLL filter
3. 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.
