It seems I found an error in LM3S8962 datasheet (revision 11108) in table 2-9 "Interrpts" at page 86:
Vector number 25 - PWM Fault Interrupt with number 9 is ommited in document but actually is supported by device.
Thanks for letting us know, Alexander. I'll pass it on to the docs team.
Regards,
Sue
