Pulse Width Modulator (PWM)
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. If
a fault interrupt is set, the corresponding FAULTn input has caused an interrupt. For the fault interrupt,
a write of 1 to that bit position clears the latched interrupt status. If an block interrupt bit is set, the
corresponding generator block is asserting an interrupt. The individual interrupt status registers,
PWMnISC, in each block must be consulted to determine the reason for the interrupt and used to
clear the interrupt.

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.
FAULT3 Interrupt Asserted
Value Description
1 An enabled interrupt for the fault condition for PWM generator
3 is asserted or is latched.
0 The fault condition for PWM generator 3 has not been asserted
or is not enabled.
Writing a 1 to this bit clears it and the INTFAULT3 bit in the PWMRIS
register.
FAULT2 Interrupt Asserted
Value Description
1 An enabled interrupt for the fault condition for PWM generator
2 is asserted or is latched.
0 The fault condition for PWM generator 2 has not been asserted
or is not enabled.
Writing a 1 to this bit clears it and the INTFAULT2 bit in the PWMRIS
register.
