16.25.10 PSC 2 Configuration Register – PCNF2
7710E–AVR–08/10
PSC 0 Configuration Register – PCNF0
PSC 1 Configuration Register – PCNF1
The Output Compare Registers RA, RB, SA and SB contain a 12-bit value that is continuously
compared with the PSC counter value. A match can be used to generate an Output Compare
interrupt, or to generate a waveform output on the associated pin.
The Output Compare Registers RB contains also a 4-bit value that is used for the flank width
modulation.
The Output Compare Registers are 16bit and 12-bit in size. To ensure that both the high and low
bytes are written simultaneously when the CPU writes to these registers, the access is per-
formed using an 8-bit temporary high byte register (TEMP). This temporary register is shared by
all the other 16-bit registers.
The PSC n Configuration Register is used to configure the running mode of the PSC.
• Bit 7 - PFIFTYn: PSC n Fifty
Writing this bit to one, set the PSC in a fifty percent mode where only OCRnRBH/L and OCRn-
SBH/L are used. They are duplicated in OCRnRAH/L and OCRnSAH/L during the update of
OCRnRBH/L. This feature is useful to perform fifty percent waveforms.
• Bit 6 - PALOCKn: PSC n Autolock
When this bit is set, the Output Compare Registers RA, SA, SB, the Output Matrix POM2 and
the PSC Output Configuration PSOCn can be written without disturbing the PSC cycles. The
update of the PSC internal registers will be done at the end of the PSC cycle if the Output Com-
pare Register RB has been the last written.
When set, this bit prevails over LOCK (bit 5)
• Bit 5 – PLOCKn: PSC n Lock
When this bit is set, the Output Compare Registers RA, RB, SA, SB, the Output Matrix POM2
and the PSC Output Configuration PSOCn can be written without disturbing the PSC cycles.
The update of the PSC internal registers will be done if the LOCK bit is released to zero.
• Bit 4:3 – PMODEn1: 0: PSC n Mode
Select the mode of PSC.
