Programmable Divider
The E016 has been designed with a control pin which
makes it ideal for use as an 8-bit programmable divider. The
TCLD pin (load on terminal count), when asserted, reloads the
data present at the parallel input pin (Pn's) upon reaching
terminal count (an all 1s state on the outputs). Because this
feedback is built internal to the chip, the programmable
division operation will run at very nearly the same frequency
as the maximum counting frequency of the device. Figure 2
below illustrates the input conditions necessary for utilizing
the E016 as a programmable divider set up to divide by 113.
To determine what value to load into the device to accomplish
the desired division, the designer simply subtracts the binary
equivalent of the desired divide ratio for the binary value for
256. As an example for a divide ration of 113:
PN's = 256
–
113 = 8F
16
= 1000 1111

Forcing this input condition, as per the set-up in Figure 2, will
result in the waveforms of Figure 3. Note that the TC output
