Multiple setting with the zero mark
The following 󹪝gure shows multiple setting of counter 1 with the zero mark. In the case
represented here, only ENSET_UP is set, i.e., the counter is set during up counting.
The relevant counter is set with each 󹪝rst rising edge of the zero mark as long as ENSET_UP and
input 1I2 are set.
The situation is analogous for counter 2 with input 2I2.
