TSD0
33
O Audio transmit serial data output 0.
SEL_PLL0 I Refer to the description and matrix for SEL_PLL2 pin 32.
TSD1
36
O Audio transmit serial data output 1.
SEL_PLL1 I Refer to the description and matrix for SEL_PLL2 pin 32.
TSD2 37 O Audio transmit serial data output 2. This pin must be pulled down to VSS via a
4.7-k: resistor for proper operation.
TSD3 38 O Audio transmit serial data output 3.
MCLK 39 I/O Audio master clock for audio DAC.
TBCK 40 I/O Audio transmit bit clock. TBCK is an input during reset and subsequently is
programmed as an output via the AUDIOXMT register (addr 0x2000D00Ch, bit 4).
SEL_PLL3
41
I Clock source select. Strapped to VCC or ground via 4.7-k: resistor; read only
during reset.
SPDIF_OUT O S/PDIF output.
SPDIF_IN 42 I S/PDIF input; (5V tolerant input).
RSD 45 I Audio receive serial data; (5V tolerant input).
RWS 46 I Audio receive frame sync; (5V tolerant input).
RBCK 47 I Audio receive bit clock; (5V tolerant input).
CAMIN3
