ABSTRACT:
Referring to FIGS. 1, 4, and 5, I/O control modules (IOCMs 25-29) include pin/status buses (75-77) which allow the transfer of pin information between integrated circuit pins (31-35) and one or more channels in IOCMs (25-29). In one embodiment, a pins/status bus (e.g. 76) may be programmably configured to permit the logical combination of the outputs of multiple channels (e.g. 160, 161, 185) in order to determine the logic state of an output pin (165). In one embodiment, the output event bus portion (e.g. 132) of a pin/status bus (e.g. 76) includes one or more set conductors (137), one or more clear conductors (138), and one or more toggle conductors (139), which may be wire-NOR conductors.
