# Low Power Stereo Playback
# ---------------------------------------------
# PowerTune mode PTM_P1 is used for low
# power 16-bit audio.
#
# For normal USB Audio, no hardware change
# is required.
#
# If using an external interface, SW2.4 and
# SW2.5 of the USB-ModEVM must be set to
# HI and clocks can be connected to J14 of
# the USB-ModEVM.
#
# Audio is routed to both headphone and
# line outputs.
