Pulse Width Modulator (PWM)
Register 12: PWM0 Raw Interrupt Status (PWM0RIS), offset 0x048
provide the current set of interrupt sources that are asserted, regardless of whether they cause an
interrupt to be asserted to the controller. Bits set to 1 indicate the latched events that have
occurred; a 0 bit indicates that the event in question has not occurred.
