7734P–AVR–08/10
PSCR Input A Control Register – PFRC0A
PSCR Input B Control Register – PFRC0B
• Bit 5- PBFM01: Balance Flank Width Modulation, bit 1
Defines the Flank Width Modulation, together with PBFM00 bit.
Table 13-13.

• Bit 4 – PAOC0B : PSCR Asynchronous Output Control B
When this bit is set, Fault input selected to block B can act directly to PSCOUT01 output. See
Section “PSCR Input Configuration”, page 159.
• Bit 3 – PAOC0A : PSCR Asynchronous Output Control A
When this bit is set, Fault input selected to block A can act directly to PSCOUT00 output. See
Section “PSCR Input Configuration”, page 159.
• Bit 2- PBFM00: Balance Flank Width Modulation, bit 0
Defines the Flank Width Modulation, together with PBFM01 bit
• Bit 1 – PCCYC0 : PSCR Complete Cycle
When this bit is set, the PSCR completes the entire waveform cycle before halt operation requested by
clearing PRUN0. This bit is not relevant in slave mode (PARUN0 = 1).
• Bit 0 – PRUN0 : PSCR Run
Writing this bit to one starts the PSCR.
When set, this bit prevails over PARUN0 bit.

Description
Flank Width Modulation operates on RB (On-Time 1 only).
Flank Width Modulation operates on RB + RA (On-Time 0 and On-Time
1).
Flank Width Modulation operates on SB (Dead-Time 1 only)
Flank Width Modulation operates on SB +SA (Dead-Time 0 and Dead-
Time 1).
