• Bit 2 – PEV1 : PSC External Event 1 Interrupt
This bit is set by hardware when an external event which can generates a fault on module 1
occurs.
Must be cleared by software by writing a one to its location.
This bit can be read even if the corresponding interrupt is not enabled (PEVE1 bit = 0).
• Bit 1 – PEV0 : PSC External Event 0 Interrupt
This bit is set by hardware when an external event which can generates a fault on module 0
occurs.
Must be cleared by software by writing a one to its location.
This bit can be read even if the corresponding interrupt is not enabled (PEVE0 bit = 0).
• Bit 0 – PEOP : PSC End Of Cycle Interrupt
This bit is set by hardware when an “end of PSC cycle” occurs.
Must be cleared by software by writing a one to its location.
This bit can be read even if the corresponding interrupt is not enabled (PEOPE bit = 0).
