PRODUCTION DATA.
The eQEP module sets the EQEPERR signal output whenever a phase error is detected in its inputs EQEPxA and EQEPxB. This error signal from both the eQEP modules is input to the connection selection multiplexer. This multiplexer is defined in Table 6-3. As shown in Figure 6-6, the output of this selection multiplexer is inverted and connected to the TZ4n trip-zone input of all ePWMx modules. This connection allows the application to define the response of each ePWMx module on a phase error indicated by the eQEP modules.
