The logic connected to the DCSI port does not have to be disabled. The user can make adjustments to the configuration as
needed (for example ADC and DAC gain). A reset to the TLV320AIC10 codec will reset all of the internal registers. As a
result, the TLV320AIC10 must be reconfigured following a reset.
