HP Detection Options

Use this section of the menu to enable or disable the HP insertion detection process. You can also the
HDTI pin logical polarity using the drop-down list box.

HP COM Short Detection Options

This section of the menu allows you to enable or disable HP COM port short detection. When short
detection recovery is set to Release, the status bit will automatically reset to '0'.

HP Short Detection, L-Ch; HP Detection, R-Ch

These sections of the menu enable or disable HP short detection for the left channel and right channel,
respectively. When short detection recovery is set to Release, the status bit will automatically reset to '0'.

Speaker Short Detection, L-Ch; Speaker Short Detection, R-Ch

These menu sections enable or disable speaker short detection for the left channel and right channel,
respectively. When short detection recovery is set to Release, the status bit will automatically reset to '0'.
