Interface boards

Three interface boards are included: analog in, S/PDIF coax and S/PDIF optical. These are plugged in to the J1
digital I/O breakout header for simple evaluation.
Figure 3 Interface boards
There is no need to configure the MA2304xNS when using these interface boards, as its digital audio output
format matches the MA2304xNS defaults.
Note that the interface boards are not compatible with a 1.8 V supply. When using the onboard buck converter,
ensure that the MA2304xNS board's VDD_SEL jumper is configured for 3.3 V (pins 1 and 2).
