2.4.10 KWV11–S Programmable Real-Time Clock
The KWV11–S is a programmable real-time clock that can be programmed
to count from one to five crystal-controlled frequencies, from an external
frequency or event, or from a 50-Hz or 60-Hz line frequency on the Q22-
bus. The board can generate interrupts or can synchronize the processor
to external events. The KWV11–S clock is functionally equivalent to the
KWV11–C.
