(9-3) Sampling frequency: 48kHz
18.4320 MHz oscillation
Error 37: PLL DAC serial transfer interrupt is not detected.
Sampling frequency: 48kHz is set to PLL DAC. When error is not detected, a message is output which prompts key input. Observe
output waveform at the terminal CXD8696R SCK02.
(9-4) Sampling frequency: 96 kHz
36.8640 MHz oscillation
Error 37: PLL DAC serial transfer interrupt is not detected.
Sampling frequency: 96 kHz is set to PLL DAC. When error is not detected, a message is output which prompts key input. Observe
output waveform at the terminal CXD8696R SCK02.
(9-5) Audio digital output
ROM audio data→ARP→AVD→Digital Audio I/F output
Error 10: Data transfer from ARP→AV Decoder is not possible.
37: PLL DAC serial transfer interrupt is not detected.
The AC3-Audio bit stream data that is stored in ROM, is transferred to AV decoder through ARP and is output to Digital Audio I/F.
When error is not detected, a message is output which prompts key input. The analog output is muted.
(9-6) Audio digital mute
ROM audio data→ARP→AVD→Digital Audio I/F output
Error 10: Data transfer from ARP→to AV decoder is not possible.
37: PLL DAC serial transfer interrupt is not detected.
Bit stream of AC-3 Audio that is stored in ROM is sent to the AV decoder through ARP, and is output to Digital Audio I/F. At this time,
the mute signal is turned on and off every other time four times, then is output.
First time: Mute OFF Sound can be heard
Second time: Mute ON
Third time: Mute OFF Sound can be heard
Fourth time: Mute ON
When error is not detected, a message is output which prompts key input.
(9-7) MPEG audio analog output
ROM audio data→ARP→AVD→2 ch DAC→Analog Audio Out
Error 10: Data transfer from ARP→ to AV decoder is not possible.
35: 2 ch DAC serial transfer interrupt is not detected.
37: PLL DAC serial transfer interrupt is not detected.
Bit stream data of MPEG-audio that is stored in ROM is sent to AV decoder through ARP, and is output in analog form from 2 ch DAC.
When error is not detected, a message is output which prompts key input.
(9-8) Dual DAC (serial)
ROM audio data→ARP→AVD→2 ch DAC→Analog Audio Out (Attenuation)
Error 10: Data transfer from ARP→ to AV decoder is not possible.
35: 2 ch DAC serial transfer interrupt is not detected.
37: PLL DAC serial transfer interrupt is not detected.
Bit stream data of MPEG-audio that is stored in ROM is sent to AV decoder through ARP, and is output in analog form from 2 ch DAC
after attenuation by 12 dB (-12 dB). When error is not detected, a message is output which prompts key input.
Sound cannot be heard
