2.3.7 KWV11-S Programmable Real-Time Clock
The KWVll-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 50/60 Hz line frequency on the Q-bus. The
board can generate interrupts or can synchronize the processor to external
events. The KWVll-S is functionally equivalent to a KWVll-C.
