13.7.1 Pin Description - Hardware Mode 6
Overall Device Control:
DFC0, DFC1 - Data Flow Control Inputs
DFC0 and DFC1 inputs determine the major data flow options available in Hardware mode, according to
S/AES - Serial Audio or AES3 Input Select
S/AES is connected to VD+ in Hardware mode 6, in order to select the serial audio input.
SFMT0, SFMT1 - Serial Audio Input Port Data Format Select Inputs
SFMT0 and SFMT1 select the serial audio input port format. See
OMCK - Output Section Master Clock Input
