Product speciﬁcation

Self Tuned Radio (STR)

TEA5757HL; TEA5759HL

READING DATA

While WRITE-ENABLE is LOW data can be read by the

microcontroller. At a rising edge of the BUS-CLOCK, data

is shifted out of the register. This data is available from the

point where the BUS-CLOCK is HIGH until the next rising

edge of the BUS-CLOCK occurs (see Fig.4).

To read the entire shift register 24 clock pulses are

necessary.

WRITING DATA

While WRITE-ENABLE is HIGH the microcontroller can

transmit data to the TEA5757HL; TEA5759HL (hard mute

is active). At a rising edge of the BUS-CLOCK, the register

shifts and accepts one bit into LSB. At clock LOW the

microcontroller writes data (see Fig.5).

To write the entire shift register 25 clock pulses are

necessary.
