Description
Minimum Interval
Indicates the minimum interval between two
edge interrupts in uSOFs (1 uSOF = 125us).
This is not valid for level interrupts. A count
of zero means that an interrupt occurs as
when an event occurs.
-
Number of clocks
Number of clocks that an Edge Interrupt
must be kept asserted on the interface. The
default INT pulse width is approximately
500ns. (N+1)*60MHz system clock.
Interrupt Polarity
0: active LOW
1: active HIGH
Interrupt Level
0: level trigger
1: Edge trigged. The pulse width
depends on the NO_OF_CLK bits in the
EDGEINTC register.
Globe interrupt enable
0: INT assertion disabled. INT will never
be asserted, regardless of other settings
or INT events.
1: INT assertion enabled. INT will be
asserted according to the HCINTEN
register, and event setting and
occurrence.
