Note
1. FM value of the affected oscillators:
a) FM VALUE = FM-RF + FM-IF.
READING DATA
While WREN is LOW data can be read by the
microcontroller. At a rising edge of the CLCK, data is
shifted out of the register. This data is available from the
point where the CLCK is HIGH until the next rising edge of
the CLCK occurs (see Fig.2).
To read the entire shift register 24 clock pulses are
necessary.
WRITING DATA
While WREN is HIGH the microcontroller can transmit
data to the OM5610 (hard mute is active). At a rising edge
of the CLCK, the register shifts and accepts one bit into
LSB. At CLCK LOW the microcontroller writes data
(see Fig.3).
To write the entire shift register 25 clock pulses are
necessary.
