Self Tuned Radio (STR)

TEA5757; TEA5759

Description of the bus

Table 2 Bus-clock functions

The TEA5757; TEA5759 radio has a bus which consists of

three wires, as shown in Table 1.

BUS-CLOCK

LOW

MO/ST (PIN 24)

RESULT

DESCRIPTION

BUS-CLOCK

DATA

software driven clock input

data input/output

The TEA5757; TEA5759 has a 25-bit shift register;

see Table 3 for an explanation of the shift register bits.

WRITE-ENABLE write/read input

If in search mode no transmitter can be found, all

frequency bits of the shift register are set to logic 0.

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.

The bus protocol is depicted in Figs 3 and 4.

during the search action

F.14 to F.0 (LSB) frequency

determine the tuning frequency of the radio; see Table 6

for the bit values

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.
