On-Time0/Dead-Time0 or on On-Time1/Dead-Time1.
Each PSC module generates a signal to synchronize the ADC sample and hold; synchronisa-
tion is mandatory for measurements.
This signal can be selected between all falling or rising edge of PSCOUTnA or PSCOUTnB
outputs.
In center aligned mode, OCRnRAH/L is not used, so it can be used to specified the synchroni-
zation of the ADC. It this case, it’s minimum value is 1.
As each PSC module can be dedicated for one function, each PSC has its own interrupt sys-
tem (vector ...)
List of interrupt sources:
Each PSC has two clock inputs:
Figure 14-15. Clock selection
PCLKSELn bit in PSC Control Register (PCTL) is used to select the clock source.
PPREn1/0 bits in PSC Control Register (PCTL) are used to select the divide factor of the
clock.
• Counter reload (end of On Time 1)
• PSC Input event (active edge or at the beginning of level configured event)
• PSC Mutual Synchronization Error
• CLK PLL from the PLL
