Register 8: PWM Interrupt Status and Clear (PWMISC), offset 0x01C
This register provides a summary of the interrupt status of the individual PWM generator blocks. A
bit set to 1 indicates that the corresponding generator block is asserting an interrupt. The individual
interrupt status registers in each block must be consulted to determine the reason for the interrupt,
and used to clear the interrupt. For the fault interrupt, a write of 1 to that bit position clears the latched
interrupt status.

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 an interrupt.
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.
PWM2 Interrupt Status
Indicates if the PWM generator 2 block is asserting an interrupt.
PWM1 Interrupt Status
Indicates if the PWM generator 1 block is asserting an interrupt.
PWM0 Interrupt Status
Indicates if the PWM generator 0 block is asserting an interrupt.
