CLK_SYNC
Synchronization and Filtering of External Interrupts
gate to the interrupt controller. However, the corresponding bit in ISR will be set, and
EIC_WAKE will be set.
If the CTRL.INTn bit is zero, then the corresponding bit in ISR will always be zero. Disabling an
external interrupt by writing to the DIS.INTn bit will clear the corresponding bit in ISR.
In synchronous mode the pin value of the EXTINTn pin is synchronized to CLK_SYNC, so
spikes shorter than one CLK_SYNC cycle are not guaranteed to produce an interrupt. The syn-
chronization of the EXTINTn to CLK_SYNC will delay the propagation of the interrupt to the
interrupt controller by two cycles of CLK_SYNC, see
on page 101
It is also possible to apply a filter on EXTINTn by writing a one to INTn bit in the FILTER register.
This filter is a majority voter, if the condition for an interrupt is true for more than one of the latest
three cycles of CLK_SYNC the interrupt will be set. This will additionally delay the propagation of
the interrupt to the interrupt controller by one or two cycles of CLK_SYNC, see
page 101
and
for examples (FILTER off).
