13.IC6702 (RH-iXC588WJN1Q)
This is a CPLD. By the SLOW BUS control, the extension I/O port for the reset signal and control signal sent to each device is created, and the
light control signal is generated.
14.IC6804 (VHiAK7770EQ-1Q)
This is an audio DSP, which implements the audio delay processing for the delay of the pictures of IC6201, the analog 2.1ch processing and the
SRS TruSurroundXT processing according to the I2S signal input from IC7103.
AUDIO-DSP
7 R/B# I READY BUSY
