Type
Power and Ground
6 Analog PLL analog power supply.
Power
8 Analog PLL analog ground.
Ground
3 PLL PLL digital power supply.
Power
2 PLL PLL digital ground.
Ground
Power Core power supply.
Ground Core digital ground.
Power I/O power supply. 3.3V Digital power supply.
Ground I/O digital ground.
Reset and Clock
96 I H/W reset signal. Active Low Schmitt-Trigger input.
The Schmitt-Trigger input allows a slowly rising input to reset the
chip reliably. The RESET signal must be asserted 'Low' during
power up. De-assert 'High' for normal operation.
86 Analog Crystal Oscillator input pin.
87 Analog Crystal Oscillator output pin.
PCM Audio Input/Output Interface
11 I/O PCM bit clock input/output of main 8-channel audio.
User can select the master/slave mode of this signal.
Schmitt-Trigger input.
12 I/O PCM Word clock (left-right clock) input/output of main 8-channel
audio. User can select the master/slave mode of this signal.
Schmitt-Trigger input.
I PCM serial data input of main 8-channel audio.
Schmitt-Trigger input.
19 I/O PCM bit clock input/output of 8-channel audio.
User can select the master/slave mode of this signal.
Schmitt-Trigger input.
20 I/O PCM word clock (left-right clock) input/output of sub 8-channel
audio. User can select the master/slave mode of this signal.
Schmitt-Trigger input.
I/O PCM serial data input of sub-channel audio.
User can set this sub-channel data input pins to PCM serial data
output pins. See the Control Register Description part.
