2.4.9 KWV11-S Programmable Real-Time Clock
The KWVl1-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 KWVll-S clock is functionally equivalent to the
KWVII-C.
