Fig. 12.4-20 Terminal assignment of the 2/4xcounter in the modes 8 ... 11
The modes 8 ... 11 offers four 16-bit counters which can be pre-assigned with a
starting value.
The modules differ in having different counting directions:
Mode 8:
z
Counters 0.2 and 1.2 count up
z
Counters 0.1 and 1.1 count up
Mode 9:
z
Counters 0.2 and 1.2 count down
z
Counters 0.1 and 1.1 count up
Mode 10:
z
Counters 0.2 and 1.2 count up
z
Counters 0.1 and 1.1 count down
Mode 11:
z
Counters 0.2 and 1.2 count down
z
Counters 0.1 and 1.1 count down
Each LOW-HIGH edge at input IN2 / IN3 / IN5 / IN6 (CLK) causes the associated
counter to count up and / or down, respectively.
