Clock Module
7.4.6.11 Loss-of-Clock Interrupt Request
When a loss-of-clock condition is detected, the PLL will request an interrupt if the LOCIRQ bit in
the SYNCR is set. The LOCIRQ bit has no affect in external clock mode or if LOCEN is cleared.
7.4.6.12 Alternate Clock Selection
Depending on which clock source fails, the loss-of-clock circuit switches the system clocks source
to the remaining operational clock. The alternate clock source generates the system clocks until
reset is asserted. As
self-clocked mode (SCM). The PLL remains in SCM until the next reset. When the PLL is
operating in SCM, the system frequency depends on the value in the RFD field. The SCM system
frequency stated in electrical specifications assumes that the RFD has been programmed to binary
000. If the loss-of-clock condition is due to PLL failure, the PLL reference becomes the system
clocks source until the next reset, even if the PLL regains and relocks.
A special loss-of-clock condition occurs when both the reference and the PLL fail. The failures
may be simultaneous, or the PLL may fail first. In either case, the reference clock failure takes
priority and the PLL attempts to operate in SCM. If successful, the PLL remains in SCM until the
next reset. If the PLL cannot operate in SCM, the system remains static until the next reset. Both
the reference and the PLL must be functioning properly to exit reset.
