Activation of the external latch input (“Latch”) and latching of the counter value (index 0x7000:02, 0x7000:04)
The counter value can be saved in “Latch value” either on a positive edge or a negative edge at the external latch
- “Enable latch extern on positive edge” (index 0x7000:02) / “Enable latch extern on negative edge” (index 0x7000:04)
- The function is activated by setting the bit in Enable latch extern on positive edge (index 0x7000:02) / Enable latch extern on negative edge (index 0x7000:04) to TRUE.
- The counter value in Latch value (index 0x6000:12) will be saved on the next positive/negative edge. The subsequent pulses have no influence on the latch value.
- The Latch extern valid bit (index 0x6000:02) is set to TRUE.
- After re-activation of Enable latch extern on positive edge (index 0x7000:02) / Enable latch extern on negative edge (index 0x7000:04), a new counter value at the latch input can only be written if the values of the Latch extern valid bit (index 0x6000:02) and the Latch C valid bit (index 0x6000:01) are FALSE
