When this bit is 0, the output drivers are configured in normal, single-ended mode; when this bit is 1, they are configured in balanced mode. Note that in balanced mode, the Pin Widget has twice as many pins as it does in normal mode; i.e., a stereo Pin Widget in balanced mode has four signal pins (in addition to Vref pins). However, in both modes it must appear to software as a single Pin Widget. The additional pins must be reserved to this purpose; thus, in a configuration supporting BTL outputs the additional pins may not be enumerated as a separate Pin Widget.
