Miscellaneous Control 1 (1)
VSET
0 - RMCK default function
1 - OMCK is switched to output through RMCK in the absence of input to the Receiver
0 - Transmit a 0 for the V bit, indicating that the data is valid, and is normally linear PCM
1 - Transmit a 1 for the V bit, indicating that the data is invalid or is not linear PCM audio data
0 - Normal output (default)
1 - Mute the serial audio output port
0 - Normal output (default)
1 - Mute the AES3 transmitter output
0 - Triangular PDF dither applied to output data. The level of the dither is
1 - No dither applied to output data.
00 - Active high, high output indicates an interrupt condition has occurred (default)
01 - Active low, low output indicates an interrupt condition has occurred
10 - Open drain, active low. This setting requires an external pull up resistor on the
11 - Reserved
0 - TCBL is an input (default)
1 - TCBL is an output
Controls the output of OMCK on the RMCK pin in the absence of input to the Receiver
