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.
