PTIF: PWM Time Base Interrupt bit
1 = PWM Time Base matched the value in PTPER register. Interrupt is issued according to the
0 = PWM Time Base has not matched the value in PTPER register.
IC3DRIF: IC3 Interrupt Flag/Direction Change Interrupt Flag bit
IC3 Enabled (CAP3CON<3:0>)
1 = TMR5 value was captured by the active edge on CAP3 input (must be cleared in software).
0 = TMR5 capture has not occurred.
QEI Enabled (QEIM<2:0>)
1 = Direction of rotation has changed (must be cleared in software).
0 = Direction of rotation has not changed.
IC2QEIF: IC2 Interrupt Flag/QEI Interrupt Flag bit
IC2 Enabled (CAP2CON<3:0>)
1 = TMR5 value was captured by the active edge on CAP2 input (must be cleared in software).
0 = TMR5 capture has not occurred.
QEI Enabled (QEIM<2:0>)
1 = The QEI position counter has reached the MAXCNT value or the index pulse, INDX, has
0 = The QEI position counter has not reached the MAXCNT value or the index pulse has not
IC1IF: IC1 Interrupt Flag bit
IC1 Enabled (CAP1CON<3:0>)
1 = TMR5 value was captured by the active edge on CAP1 input (must be cleared in software).
0 = TMR5 capture has not occurred.
QEI Enabled (QEIM<2:0>) and Velocity Measurement mode enabled
1 = Timer5 value was captured by the active velocity edge (based on PHA or PHB input).
0 = Timer5 value was not captured by the active velocity edge.
TMR5IF: Timer5 Interrupt Flag bit
1 = Timer5 time base matched the PR5 value (must be cleared in software).
0 = Timer5 time base did not match the PR5 value.
