Description
Serial data output to the CD block
Serial data transfer clock signal output to the CD block
Serial data latch pulse signal output to the CD block
Remote control signal input from the remote control receiver (IC781)
Not used (open)
Subcode Q data input from the CD block
Subcode Q data reading clock signal output to the CD block “L”: active
External data bus line byte selection signal input “L”: 16 bit, “H”: 8 bit (fixed at “L”)
