Masked interrupt status bits are not visible in registers ISR(5:0).
Masked interrupt status bits are visible in ISR(5:0), but they are
not visible in registers GIS.
Interrupts are generated either on activation or deactivation of
the internal interrupt source.
The following interrupts are activated both on activation and
deactivation of the internal interrupt source:
ISR2.LOS, ISR2.AIS and ISR0.PDEN
Internal second timer selected
External second timer selected
Not defined; reserved for future applications.
A Change of Frame or Multiframe Alignment COFA is detected
since the last resynchronization. The events are accumulated
in the COFA event counter COEC.(1:0).
Multiframe periods received in the asynchronous state are
accumulated in the COFA event counter COEC.(7:2).
An overflow of each counter is disabled.
Power up
Power down
All outputs are driven inactive, except the multifunction ports,
which are weakly driven high by the internal pullup devices.
