Analog value to be output

SM 335 outputs the default values at up to 3 analog outputs for comparator 1 or 2; refer to
chapter Special operating mode "Comparator" (Page 79).

Comparator time (DS1, byte 1)

SM 335 cannot generate a hardware interrupt for the end of the cycle while comparator 2
mode is enabled. It can therefore happen that SM 335 does not generate an end of cycle
interrupt for a longer time.
You can define the maximum comparator activation time by setting the comparator time.
After the active comparator time has expired, SM 335 automatically returns to the
"conditional cycle" or "free cycle" mode.
Define the comparator time in milliseconds (1 = 1 ms, 2 = 2 ms, up to 0 = 256 ms).
