PSC Control Register – PCTL
• Bit 4 – PMODE PSC Mode
Select the mode of PSC.
Table 14-10. PSC Mode Selection
• Bit 3 – POPB: PSC B Output Polarity
If this bit is cleared, the PSC outputs B are active Low.
If this bit is set, the PSC outputs B are active High.
• Bit 2 – POPA: PSC A Output Polarity
If this bit is cleared, the PSC outputs A are active Low.
If this bit is set, the PSC outputs A are active High.
• Bit 1:0 – not use
not use
• Bit 7:6 – PPRE1:0 : PSC Prescaler Select
This two bits select the PSC input clock division factor. All generated waveform will be modi-
fied by this factor.
Table 14-11. PSC Prescaler Selection
• Bit 5 – PCLKSEL: PSC Input Clock Select
This bit is used to select between CLK
Set this bit to select the fast clock input (CLK
Clear this bit to select the slow clock input (CLK
