11.10 Data Routing Control(0Ah)
SDOUT1[1:0] - Controls the data source for SDOUT1
00 - Sample Rate Converter
01 - AES3 Receiver Output
10 - SDIN (SDIN and SDOUT should be synchronous)
11 - Reserved
SDOUT2[1:0] - Controls the data source for SDOUT2
00 - Sample Rate Converter
01 - AES3 Receiver Output
10 - SDIN (SDIN and SDOUT should be synchronous)
11 - Reserved
MUTESAO1 - Mute control for the serial audio output port 1
0 - SDOUT1 not muted
1 - SDOUT1 muted (set to all zeros)
MUTESAO2 - Mute control for the serial audio output port 2
0 - SDOUT2 not muted.
1 - SDOUT2 muted (set to all zeros).
SRCD - Controls the data source of the sample rate converter
0 - Serial Audio Input Port (SDIN)
1 - AES3 Receiver Output
11.11 Serial Audio Input Data Format (0Bh)
SIMS - Master/Slave Mode Selector
0 - Serial audio input port is in slave mode. ISCLK and ILRCK are inputs.
1 - Serial audio input port is in master mode. ISCLK and ILRCK are outputs.
SISF - ISCLK Frequency. Valid only in master mode (SIMS = 1). Should be changed when PDN = 1. See
for details.
