Product specification
Self Tuned Radio (STR)
TEA5757; TEA5759
Description of the bus
The TEA5757; TEA5759 radio has a bus which consists of
three wires, as shown in Table 1.
Table 1
Bus signals
These three signals, together with the mono/stereo pin
(MO/ST; pin 24), communicate with the microcontroller.
The mono/stereo indicator has two functions, which are
controlled by the BUS-CLOCK, as shown in Table 2.
Table 2
Bus-clock functions
The TEA5757; TEA5759 has a 25-bit shift register;
see Table 3 for an explanation of the shift register bits.
If in search mode no transmitter can be found, all
frequency bits of the shift register are set to logic 0.
The bus protocol is depicted in Figs 3 and 4.

Note
1.
The output pins 30 and 31 can drive currents up to 5 mA; bits P0.19 and P1.18 control the output voltage of the
control pins P0 (pin 30) and P1 (pin 31):
a) Bit P0.19 LOW sets P0 (pin 30) to LOW.
b) Bit P0.19 HIGH sets P0 (pin 30) to HIGH.
c) Bit P1.18 LOW sets P1 (pin 31) to LOW.
d) Bit P1.18 HIGH sets P1 (pin 31) to HIGH.
