• Bit 1:0 – PSYNC0[1:0]: Synchronization Out for ADC Selection

Select the polarity and signal source for generating a signal which will be sent from module 0 to

the ADC for synchronization

18.16.3 POCRnSAH and POCRnSAL – PSC Output Compare SA Register

18.16.4 POCRnRAH and POCRnRAL – PSC Output Compare RA Register

18.16.5 POCRnSBH and POCRnSBL – PSCOutput Compare SB Register

Table 18-8. Synchronization Source Description in One Ramp Mode

PSYNCn1 PSYNCn0 Description

0 0 Send signal on leading edge of PSCOUTnA(match with OCRnSA)

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)

Send signal on trailing edge of PSCOUTnB (match with OCRnRB or

fault/retrigger on part B)

PSYNCn1 PSYNCn0 Description

Send signal on match with OCRnRA (during counting down of PSC). The

min value of OCRnRA must be 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
