DATASHEET
14
Interrupt Deassertion Interval Clear (INT_DEAS_CLR
). Writing a one
to this register clears the de-assertion counter in the IRQ Controller, thus
causing a new de-assertion interval to begin (regardless of whether or
not the IRQ Controller is currently in an active de-assertion interval).
13
Interrupt Deassertion Status (INT_DEAS_STS).
When set, this bit
indicates that the INT_DEAS is currently in a deassertion interval, and
any interrupts (as indicated by the IRQ_INT and INT_EN bits) will not be
delivered to the IRQ pin. When cleared, the INT_DEAS is currently not
in a deassertion interval, and enabled interrupts will be delivered to the
IRQ pin.
SC
0
12
Master Interrupt (IRQ_INT).
This read-only bit indicates the state of the
internal IRQ line. When set high, one of the enabled interrupts is
currently active. This bit will respond to the associated interrupts
regardless of the IRQ_EN field. This bit is not affected by the setting of
the INT_DEAS field.

8
IRQ Enable (IRQ_EN) –
This bit controls the final interrupt output to the
IRQ pin. When cleared, the IRQ output is disabled and will be
permanently deasserted. This bit only controls the external IRQ signal,
and has no effect on any of the internal interrupt status bits.
R/W
0
7-5
Reserved
RO
-
4
IRQ Polarity (IRQ_POL) –
When cleared, enables the IRQ line to
function as an active low output. When set, the IRQ output is active high.
When IRQ is configured as an open-drain output this field is ignored,
and the interrupt output is always active low.
R/W
NASR
0
3-1
Reserved
RO
-
0
IRQ Buffer Type (IRQ_TYPE) –
When cleared, enables IRQ to function
as an open-drain buffer for use in a Wired-Or Interrupt configuration.
When set, the IRQ output is a Push-Pull driver. When configured as an
open-drain output the IRQ_POL field is ignored, and the interrupt output
is always active low.
