Value Description
EPWMxINT Compare Register Selection Options:
0 Enable event time-base counter equal to CMPA when the timer is incrementing / Enable event
time-base counter equal to CMPA when the timer is decrementing / Enable event: time-base
counter equal to CMPB when the timer is incrementing / Enable event: time-base counter equal to
CMPB when the timer is decrementing to INTSEL selection mux.
1 Enable event time-base counter equal to CMPC when the timer is incrementing / Enable event
time-base counter equal to CMPC when the timer is decrementing / Enable event: time-base
counter equal to CMPD when the timer is incrementing / Enable event: time-base counter equal to
CMPD when the timer is decrementing to INTSEL selection mux.
EPWMxSOCB Compare Register Selection Options:
0 Enable event time-base counter equal to CMPA when the timer is incrementing / Enable event
time-base counter equal to CMPA when the timer is decrementing / Enable event: time-base
counter equal to CMPB when the timer is incrementing / Enable event: time-base counter equal to
CMPB when the timer is decrementing to SOCBSEL selection mux.
1 Enable event time-base counter equal to CMPC when the timer is incrementing / Enable event
time-base counter equal to CMPC when the timer is decrementing / Enable event: time-base
counter equal to CMPD when the timer is incrementing / Enable event: time-base counter equal to
CMPD when the timer is decrementing to SOCBSEL selection mux.
EPWMxSOCA Compare Register Selection Options:
0 Enable event time-base counter equal to CMPA when the timer is incrementing / Enable event
time-base counter equal to CMPA when the timer is decrementing / Enable event: time-base
counter equal to CMPB when the timer is incrementing / Enable event: time-base counter equal to
CMPB when the timer is decrementing to SOCASEL selection mux.
1 Enable event time-base counter equal to CMPC when the timer is incrementing / Enable event
time-base counter equal to CMPC when the timer is decrementing / Enable event: time-base
counter equal to CMPD when the timer is incrementing / Enable event: time-base counter equal to
CMPD when the timer is decrementing to SOCASEL selection mux.
Enable ePWM Interrupt (EPWMx_INT) Generation
0 Disable EPWMx_INT generation
1 Enable EPWMx_INT generation
ePWM Interrupt (EPWMx_INT) Selection Options
000 Reserved
001 Enable event time-base counter equal to zero. (TBCTR = 0x00)
010 Enable event time-base counter equal to period (TBCTR = TBPRD)
011 Enable event time-base counter equal to zero or period (TBCTR = 0x00 or TBCTR = TBPRD). This
mode is useful in up-down count mode.
100 Enable event time-base counter equal to CMPA when the timer is incrementing or CMPC when the
timer is incrementing
101 Enable event time-base counter equal to CMPA when the timer is decrementing or CMPC when the
timer is decrementing
110 Enable event: time-base counter equal to CMPB when the timer is incrementing or CMPD when the
timer is incrementing
111 Enable event: time-base counter equal to CMPB when the timer is decrementing or CMPD when
the timer is decrementing (*) Event selected is determined by INTSELCMP bit.
