TEA5766UK
Stereo FM radio + RDS
7.19 RDS/RBDS decoder
The RDS decoder provides block synchronization, error correction and ywheel function
for reliable extraction of RDS or RBDS block data. Different modes of operation can be
selected to t different application requirements. Availability of new data is signalled by bit
DAVFLG and output pin INTX, which generates an interrupt. Up to two blocks of data and
status information are available via the I2C-bus in a single transmission.
The behavior of the DAVFLG is described in Section 9.
7.20 Auto search and preset mode
In search mode TEA5766UK can search channels automatically.
When the INTX signal is used as an interrupt to the host processor to indicate a search
stop, the INTMSK register must be reset and only bit FRRMSK must be set. In this way
the host processor will only be interrupted when the search/preset algorithm is ready.
Search mode is initiated setting the SM bit to logic 1 in the FRQSET register. When bit
SUD is logic 0 then it searches down and when SUD is logic 1 it searches up. The tuner
starts searching at the frequency where it is or at a new start frequency programmed to
the tuner. With the Search Stop Level (SSL[1:0]) bits the minimum eld strength of
channels to be found can be set. The tuner will stop on a channel with a eld strength
equal to or higher than this reference level and then will check the IF frequency. When
both are valid the search mode stops. If the level check or the IF count fails, it continues
the search. When no channels are found the TEA5766UK stops searching when it has
reached the band-limit and bit BLFLAG goes to logic 1. A search always stops with bit
FRRFLAG being set and a hardware interrupt. Figure 4 shows this procedure.
After this interrupt the TEA5766UK will keep its status and will not update the INTREG,
FRQCHK and TUNCHK tuner registers for a period of 15.6 ms. The state of the
TEA5766UK can be checked by reading tuning registers: INTREG, FRQCHK and
TUNCHK. Table 5 shows the possible states after an auto search or a preset.
A preset is done by setting bit SM to logic 0 and writing a frequency to byte FRQSETMSB.
The tuner jumps to the selected frequency and sets bit FRRFLAG when it is ready. After
this interrupt the TEA5766UK will keep not update the tuner registers for a period of
15.6 ms. The state of the TEA5766UK can be checked by reading registers: INTFLAG,
FRQCHK and TNCTRL. Table 5 shows the possible states after an auto search or preset.
