9. GENERAL PURPOSE OUTPUTS
Three General Purpose Outputs (GPO) are provided to allow the equipment designer flexibility in configuring the
CS8416. Fourteen signals are available to be routed to any of the GPO pins. The outputs of the GPO pins are set
through the GPOxSEL[3:0] bits in the Control2 (02h) and Control3 (03h) registers. All GPO pins default to GND
after reset.
GPO pins may be configured to provide the following data:

If the input sample rate is ≤ 48 kHz, outputs a “0”. Outputs a “1” if the sample rate is ≥ 88.1 kHz.
Otherwise the output is indeterminate.
