PWM Interrupt Indication Register
| PWMIF0 | PWM Channel 0 Interrupt Status Flag is set by hardware when PWM0 down counter reaches zero, software can write 1 to clear this bit to zero. |
| PWMIF1 | PWM Channel 1 Interrupt Status Flag is set by hardware when PWM1 down counter reaches zero, software can write 1 to clear this bit to zero. |
| PWMIF2 | PWM Channel 2 Interrupt Status Flag is set by hardware when PWM2 down counter reaches zero, software can write 1 to clear this bit to zero. |
| PWMIF3 | PWM Channel 3 Interrupt Status Flag is set by hardware when PWM3 down counter reaches zero, software can write 1 to clear this bit to zero. |
