A multiprocessor switching device substantially implemented on a single
CMOS integrated circuit is described in connection with a channelized
timer for use in controlling the issuance of signals to the processor(s)
or control logic (such as interrupts, descriptors, etc.) that that
identify system-related functions for a plurality of channels. Using
control registers to select an individual bit of a multi-bit counter, a
timing interval pulse is provided for prompting signal generation that is
otherwise subject to a minimum count requirement.
