Latch inputs to the ESC can be used to capture the time-stamp or register the GPI inputs. Two latch inputs are available. Latch enables external events:
Both of the Latch inputs can be independently configured to operate on either the rising or falling edge of the signal. The LATCH events can be individually assigned either for the PDI control or EtherCAT controller control. Additionally, one shot or continuous mode is supported.
Figure 35-17 depicts the different sources for the LATCH0/1 so as to fulfill the application requirements. These are explained for possible use.
The details of connections and mux select to these muxes is shown in Table 35-12 and selection is possible individually for each of the LATCH0 or LATCH1 signal.
