PCM/I2S Selection
Several empty resistor pads are available for configuration. Zero-ohm resistors can be soldered onto them
to complete the connections, which are necessary for applications that require I2S communication. These
include A3DPDemo_SNK and HFPAGDemo (see Section 5, Settings, of the
Quick Start Guide
,
, for the full list).
There are four different configurations – two per board – that can be used to run all of the demo programs.
R31, R41, or R43 are not populated in any of these configurations. However, for other applications that
might require connection of other signals such as EVAL_I2S2ext_SDPI2, the user may make these
connections.

32.768-KHz Clock
Next to the CC256X EM connectors is a 32.768-KHz crystal oscillator circuit. This provides the slow clock
for the CC256X EM.
