Product data sheet
6.19.2 Preset mode
A preset is done by setting bit SM to logic 0 and writing a frequency to register FRQSET.
The tuner jumps to the selected frequency and sets the FRRFLAG when it is ready. After
this interrupt the TEA5760UK will not update the tuner registers for a period of 15.625 ms.
The state of the TEA5760UK can be checked by reading registers INTREG, FRQCHK and
TUNCHK.
