Activation of latch C input (“C”) and saving (“latching”) of the counter value (index 0x7000:01)

The counter value is written into “Latch value” (index 0x6000:12) when the zero pulse is present at input C.

After re-activation of “Enable latch C” (index 0x7000:01), the next counter value can be written into “Latch value” (index 0x6000:12) only if the values of the “Latch C valid” bit (index 0x6000:01) and the “Latch extern valid” bit (index 0x6000:02) are FALSE.
