Fig. 13.2−6 Terminal assignment of the 2/4xcounter in the modes 1, 3 and 5
The modes 1, 3, and 5 offer two encoders that can be pre−assigned with a starting
value.
The modes differ in the number of edges which are evaluated:
Mode 1: 1 edge
Mode 3: 2 edges
Mode 5: 4 edges
See signal characteristics.
During the counting process, a LOW level must be applied to input IN1 / IN4 (RES).
A HIGH level deletes the counter.
When the counter reaches zero, the output OUT0 / OUT1 is 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.
