Fig. 12.4−45 Terminal assignment of the 2/4xcounter in the modes 23 ... 26
In the modes 23 to 26, two 32−bit counters are available, which are controlled via
a gate signal (gate). A starting value and a comparison value can be assigned to
each counter.
The modes differ in triggering the outputs Out0 / Out 1 differently (set or reset
function) and the counting direction:
Modes 23 and 25: Upcounter.
Modes 24 and 26: Downcounter
If a HIGH level is applied to input IN3 / IN6 (GATE), the counter is incremented or
decremented by 1 with each LOW/HIGH edge.
During the counting process, a LOW level must be applied to input IN1 / IN4 (RES).
A HIGH level deletes the counter.
Modes 23 and 24 (set function):
l The signal at output OUT0 / OUT1 is set to HIGH level on counter loading.
l When reaching the value loaded in Compare, the output signal is set to LOW
level. The counter continues to run.
Modes 25 and 26 (reset function):
l The signal at output OUT0 / OUT1 is set to LOW level on counter loading.
l When reaching the value loaded in Compare, the output signal is set to
HIGH level (modes 25 and 26). The counter continues to run.
