Register 12: PWM0 Raw Interrupt Status (PWM0RIS), offset 0x048
This register provides 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.
