Abstract
A timer system comprises a plurality of timer channels serviced by a single service processor. Each of the timer channels is capable of both input (capture) and output (match) functions. The microprogrammed service processor is responsible for configuring each of the channels for their intended uses and for responding to service requests generated by the channels in response to the occurrence of timer events. Features of the timer channels include the ability to continuously execute capture functions without generating service requests, the ability to execute a single capture function and service request and protect the captured value from being overwritten until the service request has been responded to and the ability to combine match and capture functions in such a way as to place a time-out window on the capture event.
