PTIF: PWM Time Base Interrupt bit
1 = PWM time base matched the value in the PTPER registers. Interrupt is issued according to the
0 = PWM time base has not matched the value in the PTPER registers
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 been
0 = The QEI position counter has not reached the MAXCNT value or the index pulse has not been
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>), Velocity Measurement mode Enabled (VELM = 0 in QEICON register):
1 = Timer5 value was captured by the active velocity edge (based on PHA or PHB input). CAP1REN
