FUNCTION

D15 DIFFIN 0 R/W Single-ended or Differential Output Selection.

0 => Single-ended output (headset/lineout) selected for SPK1 and SPK2 drivers

1 => Differential output (handset) selected for SPK1 and OUT32N drivers

Note: When bit D15=1, both SPK1 and OUT32N drivers should be power−up. Otherwise the

TSC2101 automatically power−down both SPK1 and OUT32N drivers.
