Register 23: PWM0 Interrupt Status and Clear (PWM0ISC), offset 0x04C
Register 24: PWM1 Interrupt Status and Clear (PWM1ISC), offset 0x08C
Register 25: PWM2 Interrupt Status and Clear (PWM2ISC), offset 0x0CC
Register 26: PWM3 Interrupt Status and Clear (PWM3ISC), offset 0x10C
These registers provide the current set of interrupt sources that are asserted to the controller
(PWM0ISC controls the PWM generator 0 block, and so on). Bits set to 1 indicate the latched events
that have occurred; bits set to 0 indicate that the event in question has not occurred. These are
R/W1C registers; writing a 1 to a bit position clears the corresponding interrupt reason.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Comparator B Down Interrupt
Indicates that the counter has matched the comparator B value while
counting down.
Comparator B Up Interrupt
Indicates that the counter has matched the comparator B value while
counting up.
Comparator A Down Interrupt
Indicates that the counter has matched the comparator A value while
counting down.
Comparator A Up Interrupt
Indicates that the counter has matched the comparator A value while
counting up.
Counter=Load Interrupt
Indicates that the counter has matched the PWMnLOAD register.
Counter=0 Interrupt
Indicates that the counter has matched 0.
