This trip zone input is dedicated to eQEPx error indications. There are 2 eQEP modules on this device. Each eQEP module indicates a phase error by driving its EQEPxERR output high. The following control registers allow the application to configure the trip zone input (TZ4n) to each ePWMx module based on the requirements of the applicationapplication's requirements.
ePWMx | CONTROL FOR TZ4n = NOT(EQEP1ERR OR EQEP2ERR) | CONTROL FOR TZ4n = NOT(EQEP1ERR) | CONTROL FOR TZ4n = NOT(EQEP2ERR) |
---|---|---|---|
ePWM1 | PINMMR167[2:0] = 001 | PINMMR167[2:0] = 010 | PINMMR167[2:0] = 100 |
ePWM2 | PINMMR167[10:8] = 001 | PINMMR167[10:8] = 010 | PINMMR167[10:8] = 100 |
ePWM3 | PINMMR167[18:16] = 001 | PINMMR167[18:16] = 010 | PINMMR167[18:16] = 100 |
ePWM4 | PINMMR167[26:24] = 001 | PINMMR167[26:24] = 010 | PINMMR167[26:24] = 100 |
ePWM5 | PINMMR168[2:0] = 001 | PINMMR168[2:0] = 010 | PINMMR168[2:0] = 100 |
ePWM6 | PINMMR168[10:8] = 001 | PINMMR168[10:8] = 010 | PINMMR168[10:8] = 100 |
ePWM7 | PINMMR168[18:16] = 001 | PINMMR168[18:16] = 010 | PINMMR168[18:16] = 100 |
The EQEPxERR signal is an active high signal coming out of EQEPx module. As listed in Table 8-3, the selected combination of the EQEPxERR signals must be inverted before connecting to the TZ4n input of the ePWMx modules.
