The digital I/O breakout header (J1) provides access to audio and control signals (I
well as several MA2304xNS GPIO pins and the onboard VDD supply (3.3 or 1.8 V). The J1 header is meant for use
with the interface boards, and/or external connections (external I
debugging. The J2 header contains exactly the same signals as J1 but can be used for monitoring the I/O digital
