IC380 (CXD8603R) n Audio signal output
The bit stream data including AC-3 audio stored in IC093 (ROM)
are transferred to the DRAM of IC181 (CXD8663Q). Then, the
data are flown to the IC380 (CXD8603R) via IC217 (CXD8598R)
to regenerate audio signals.
As SERR signal from IC181 (CXD8663Q) to IC217 (CXD8598R)
is not initialized, this signal line is shut off and fixed to “high” be-
fore checking.
This diagnosis turns on all channels to turn on both analog and
digital outputs.
If no error is detected, a sound is generated, then a message is out-
put and the controller waits for key entry.
