Bit

Initial Value
• Bit 7 – POACnB : PSC n Output B Activity
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
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.
This feature is useful to detect that a PSC output doesn’t change due to a freezen external input
signal.
• Bit 5 – PSEIn : PSC n Synchro Error Interrupt
This bit is set by hardware when the update (or end of PSC cycle) of the PSCn configured in
auto run (PARUNn = 1) does not occur at the same time than the PSCn-1 which has generated
the input run signal. (For PSC0, PSCn-1 is PSC2).
Must be cleared by software by writing a one to its location.
This feature is useful to detect that a PSC doesn’t run at the same speed or with the same phase
than the PSC master.
• Bit 4 – PEVnB : PSC n External Event B Interrupt
This bit is set by hardware when an external event which can generates a capture or a retrigger
from Retrigger/Fault block B 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 (PEVEnB bit = 0).
• Bit 3 – PEVnA : PSC n External Event A Interrupt
This bit is set by hardware when an external event which can generates a capture or a retrigger
from Retrigger/Fault block A 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 (PEVEnA bit = 0).
