Table 16-13. PSC n Mode Selection
• Bit 2 – POPn: PSC n Output Polarity
If this bit is cleared, the PSC outputs are active Low.
If this bit is set, the PSC outputs are active High.
• Bit 1 – PCLKSELn: PSC n Input Clock Select
This bit is used to select between CLKPF or CLKPS clocks.
Set this bit to select the fast clock input (CLKPF).
Clear this bit to select the slow clock input (CLKPS).
• Bit 0 – POME2: PSC 2 Output Matrix Enable (PSC2 only)
Set this bit to enable the Output Matrix feature on PSC2 outputs. See
159.
When Output Matrix is used, the PSC n Output Polarity POPn has no action on the outputs.
• Bit 7:6 – PPRE01:0 : PSC 0 Prescaler Select
This two bits select the PSC input clock division factor. All generated waveform will be modified
by this factor.
Table 16-14. PSC 0 Prescaler Selection
• Bit 5 – PBFM0 : 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.
