PSYNCn1 PSYNCn0 Description
0 0 Send signal on leading edge of PSCOUTnA(match with OCRnSA)
0 1
Send signal on trailing edge of PSCOUTnA(match with OCRnRA or
fault/retrigger on part A)
1 0 Send signal on leading edge of PSCOUTnB (match with OCRnSB)
1 1
Send signal on trailing edge of PSCOUTnB (match with OCRnRB or
fault/retrigger on part B)
Table 18-9. Synchronization Source Description in Centered Mode
PSYNCn1 PSYNCn0 Description
0 0
Send signal on match with OCRnRA (during counting down of PSC). The
min value of OCRnRA must be 1.
0 1
Send signal on match with OCRnRA (during counting up of PSC). The
min value of OCRnRA must be 1.
1 0 no synchronization signal
1 1 no synchronization signal
