R
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.3).
To read the entire shift register 24 clock pulses are
necessary.

While WRITE-ENABLE is HIGH the microcontroller can
transmit data to the TEA5762 (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.4).
To write the entire shift register 25 clock pulses are
necessary.
