Note that it is not possible to connect a signal in one group directly to a
signal in a different group (analogous to wiring from one patch bay to
another). However, Group D is largely devoted to routing in this vein.

Pins Interface

Within the context of the SRU, physical connections to the DAI pins are
replaced by a logical interface known as a pin buffer. This is a three termi-
nal active device capable of sourcing/sinking output current when its
driver is enabled, and passing external input signals when disabled. Each
pin has a pin input, output, and enable as shown in
inputs and the outputs are defined with respect to the pin, similar to a
peripheral device. This is consistent with the SRU naming convention.
