Functional Description
Subcode interface
The LC89170M accepts subcode data from the DSP using the EXCK, SBSO, SCOR, and WFCK pins. Figure 1 shows
the timing.
SW1 sets the input or output state for the EXCK pin. This pin is provided for cases where a subcode interface shift clock
source, such as a CD-G decoder circuit, is present in the vicinity of the LC89170M. Figure 2 shows usage examples.
The SW2 is selected according to the subcode block period, TB, input to the SCOR pin.
