Fig. 13.2−71 Terminal assignment of the 2/4xcounter in the modes 36 ... 38
The modes 36 to 38 offer two encoders that can be pre−assigned with a starting
value.
The modes differ in the number of edges which are evaluated:
Mode 36: 1 edge
Mode 37: 2 edges
Mode 38: 4 edges
See signal characteristics.
During the counting process, a HIGH level must be applied to input IN1 / IN4
(GATE). With a LOW level the counter content is frozen.
When the counter reaches zero, the output OUT0 / OUT1 is set to HIGH level for
at least 100 ms, even if the counter continues to count. When the counter stops
at zero, the output OUT0 / OUT1 remains on the HIGH level.
