PCTL – PSC Control Register
PMICn – PSC Module n Input Control Register
• Bit 1:0 – Res: Reserved
These bits are reserved and will always read as zero.
• Bit 7:6 – PPRE1:0: PSC Prescaler Select
This two bits select the PSC input clock division factor. All generated waveform will be modified
by this factor.
Table 17-11. 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
• Bit 4:2 – Res: Reserved
These bits are reserved and will always read as zero.
• Bit 1 – PCCYC: PSC Complete Cycle
When this bit is set, the PSC completes the entire waveform cycle before halt operation
requested by clearing PRUN.
• Bit 0 – PRUN: PSC Run
Writing this bit to one starts the PSC.
The Input Control Registers are used to configure the 2 PSC’s Retrigger/Fault block A & B. The
2 blocks are identical, so they are configured on the same way.
• Bit 7 – POVENn: PSC Module n Overlap Enable
Set this bit to disactivate the Overlap Protection. See
