115 Pin groups
118 Many controllers need to deal with groups of pins, so the pin controller
119 subsystem has a mechanism for enumerating groups of pins and retrieving the
126 These two groups are presented to the pin control subsystem by implementing

530   It is possible to map several groups to the same combination of device,
