DIR-INC Mode

In DIR-INC mode a change in angle for both directions

of rotation generates an output pulse for signal CLK

(pin A). Signal DIR (pin B) gives the direction of ro-

tation. This mode permits the operation of external

binary counter modules (such as 74HC/HCT191, for

example), with signal NCLR (pin C) being used to re-

set the external counter. With a rising edge at CLK

the counter status is counted up or down, depending

on the value of the DIR signal. A low level at DIR trig-

gers a countup; a high level causes the setup to count

down. Figure 17 shows a countup sequence followed

by a countdown sequence, both across the zero posi-

tion.
