Register 19: PWM0 Raw Interrupt Status (PWM0RIS), offset 0x048
Register 20: PWM1 Raw Interrupt Status (PWM1RIS), offset 0x088
Register 21: PWM2 Raw Interrupt Status (PWM2RIS), offset 0x0C8
Register 22: PWM3 Raw Interrupt Status (PWM3RIS), offset 0x108
These registers provide the current set of interrupt sources that are asserted, regardless of whether
they cause an interrupt to be asserted to the controller (PWM0RIS 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.

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 Status
Indicates that the counter has matched the comparator B value while
counting down.
Comparator B Up Interrupt Status
Indicates that the counter has matched the comparator B value while
counting up.
Comparator A Down Interrupt Status
Indicates that the counter has matched the comparator A value while
counting down.
Comparator A Up Interrupt Status
Indicates that the counter has matched the comparator A value while
counting up.
Counter=Load Interrupt Status
Indicates that the counter has matched the PWMnLOAD register.
Counter=0 Interrupt Status
Indicates that the counter has matched 0.
