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 cause an interrupt to be asserted to the controller. The fault interrupt is latched on detection;
it must be cleared through the PWM Interrupt Status and Clear (PWMISC) register (see page 580).
The PWM generator interrupts simply reflect the status of the PWM generators; they are cleared
via the interrupt status register in the PWM generator blocks. Bits set to 1 indicate the events that
are active; zero bits indicate that the event in question is not active.

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.
Fault Interrupt Asserted
Indicates that the fault input is asserting.
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

PWM2 Interrupt Asserted
Indicates that the PWM generator 2 block is asserting its interrupt.
PWM1 Interrupt Asserted
Indicates that the PWM generator 1 block is asserting its interrupt.
PWM0 Interrupt Asserted
Indicates that the PWM generator 0 block is asserting its interrupt.
