16.25.12 PSC 1 Control Register – PCTL1
7710E–AVR–08/10
• Bit 4 – PAOC0B : PSC 0 Asynchronous Output Control B
When this bit is set, Fault input selected to block B can act directly to PSCOUT01 output. See
See “PSC Input Configuration” on page
• Bit 3 – PAOC0A : PSC 0 Asynchronous Output Control A
When this bit is set, Fault input selected to block A can act directly to PSCOUT00 output. See
See “PSC Input Configuration” on page
• Bit 2 – PARUN0 : PSC 0 Autorun
When this bit is set, the PSC 0 starts with PSC2. That means that PSC 0 starts :
Thanks to this bit, 2 or 3 PSCs can be synchronized (motor control for example)
• Bit 1 – PCCYC0 : PSC 0 Complete Cycle
When this bit is set, the PSC 0 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 : PSC 0 Run
Writing this bit to one starts the PSC 0.
When set, this bit prevails over PARUN0 bit.
• Bit 7:6 – PPRE11:0 : PSC 1 Prescaler Select
This two bits select the PSC input clock division factor.All generated waveform will be modified
by this factor.
Table 16-15. PSC 1 Prescaler Selection
• Bit 5 – PBFM1 : Balance Flank Width Modulation
When this bit is clear, Flank Width Modulation operates on On-Time 1 only.
When this bit is set, Flank Width Modulation operates on On-Time 0 and On-Time 1.
• Bit 4 – PAOC1B : PSC 1 Asynchronous Output Control B
When this bit is set, Fault input selected to block B can act directly to PSCOUT11 output. See
