16. D/A converter interface; pin 31: WCLK, pin 33: LRCLK, pin 35: DFOUT, pin 36: DACLK

Data for the D/A converter is output MSB first from DFOUT synchronized with the falling edge of DACLK.

Command

CD-ROM XA

CONT AND CD-ROM XA RESET

RES = low

○

When the CD-ROM XA command described above is issued, data that is neither interpolated nor muted will be

output from the DFOUT and DOUT pins. (This command is used for CD-ROM XA applications.) The CD-ROM XA

reset command also functions as a pin 60 CONT reset, so caution is required.

17. CD-ROM outputs; Pin 39: CK2, pin 37: LRSY, pin 40: ROMOUT, pin 42: C2F, pin 41: C2FCLK

Data is output MSB first from the ROMOUT pin in synchronization with the LRSY signal. This data is appropriate

for input to a CD-ROM LSI, since it is not interpolated, previous value held, or processed by the digital filter circuits.

CK2 is a 2.1168 MHz clock, and data is output on the CK2 rising edge. C2F is the flag information for data in 8-bit

units. C2FCLK is the synchronization signal for that flag.
