• Bit 4:3 – PMODEn1: 0: PSC n Mode
Select the mode of PSC.
Table 12-13.
• 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
When Output Matrix is used, the PSC n Output Polarity POPn has no action on the outputs.
The PSC n Extended Configuration Register is used to configure the running mode of the PSC
• Bit 7, 6, 5– PASDLKn(2:0): Analog Synchronization Output Delay or Input Blanking select
Defines the modes for Analog signal synchronization delay or Input Blanking.
