12.23 PSC Clock Sources
12.24 Interrupts

AT90PWM81
According to the architecture of the PSC synchronization which build a “daisy-chain on the PSC run sig-
nal” between the three PSC, only the fault event (mode 7) which is able to “stop” the PSC through the
PRUN bits is transmitted along this daisy-chain.
A PSC which receive its Run signal from the previous PSC transmits its fault signal (if enabled) to this
previous PSC. So a slave PSC propagates its fault events when they are configured and enabled.
PSC must be able to generate high frequency with enhanced resolution.
Each PSC has two clock inputs:
Figure 12-42. Clock selection
PCLKSELn bit in PSC n Configuration register (PCNFn) is used to select the clock source.
PPREn1/0 bits in PSC n Control Register (PCTLn) are used to select the divide factor of the clock.
Table 12-10.
This section describes the specifics of the interrupt handling as performed in AT90PWM81.
