Bit
Read/Write
Initial Value
• Bit 5 – PSEIEn : PSC n Synchro Error Interrupt Enable
When this bit is set, the PSEIn bit (if set) generate an interrupt.
• Bit 4 – PEVEnB : PSC n External Event B Interrupt Enable
When this bit is set, an external event which can generates a capture from Retrigger/Fault block
B generates also an interrupt.
• Bit 3 – PEVEnA : PSC n External Event A Interrupt Enable
When this bit is set, an external event which can generates a capture from Retrigger/Fault block
A generates also an interrupt.
• Bit 0 – PEOPEn : PSC n End Of Cycle Interrupt Enable
When this bit is set, an interrupt is generated when PSC reaches the end of the whole cycle.

Initial Value
• Bit 7 – POACnB : PSC n Output B Activity (not implemented on AT90PWM2/3)
This bit is set by hardware each time the output PSCOUTn1 changes from 0 to 1 or from 1 to 0.
Must be cleared by software by writing a one to its location.
This feature is useful to detect that a PSC output doesn’t change due to a freezen external input
signal.
• Bit 6 – POACnA : PSC n Output A Activity (not implemented on AT90PWM2/3)
This bit is set by hardware each time the output PSCOUTn0 changes from 0 to 1 or from 1 to 0.
Must be cleared by software by writing a one to its location.
