Figure 4-11 Dividing The Rate Of The Master Clock - Keithley DAS-800 series User Manual

Internal
clock
4-14
Figure 4-11 illustrates the use of C/T0 on the 8254 on board 1 to divide
the rate of the master clock by the programmed count; this allows you to
synchronize conversions on board 1 to a rate different from that of the
master board. Note that when you use C/T0 to divide the rate of the
master clock, C/T0 must be configured for counter/timer mode 2 (rate
generator mode). Refer to page 2-21 or to your 8254 documentation for
more information.
