LED Function Indicators
Several LEDs are provided to indicate board func-
tions. D9 indicates that power is present to the
VD+/VA+ section of the CS8416 and CS8406.
D11, D12, and D13 indicate the status of the
NV/RERR, AUDIO, and 96 kHz output of the
CS8416 in Hardware Mode. See the CS8416 data
sheet for an explanation of the conditions that acti-
vate each of these outputs.
