Register 7: PWM Raw Interrupt Status (PWMRIS), offset 0x018
This register provides the current set of interrupt sources that are asserted, regardless of whether
they are enabled to cause an interrupt to be asserted to the interrupt controller. The fault interrupt
is asserted based on the fault condition source that is specified by the PWMnCTL, PWMnFLTSRC0
and PWMnFLTSRC1 registers. The fault interrupt is latched on detection and must be cleared
through the PWM Interrupt Status and Clear (PWMISC) register. The actual value of the FAULTn
signals can be observed using the PWMSTATUS register.
The PWM generator interrupts simply reflect the status of the PWM generators and are cleared via
the interrupt status register in the PWM generator blocks. If a bit is set, the event is active; if a bit
is clear the event is not active.

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.
