PRODUCTION DATA.
These 3 trip zone inputs are driven by external circuits and are connected to device-level inputs. These signals are either connected asynchronously to the ePWMx trip zone inputs, or double-synchronized with VCLK3, or double-synchronized and then filtered with a 6-cycle VCLK3-based counter before connecting to the ePWMx (see Figure 6-2). By default, the trip zone inputs are asynchronously connected to the ePWMx modules.
