Type ET/R
Edge triggered interrupt, on the rising edge.
Type ET/F
Edge triggered interrupt, on the falling edge.
Type LT
Level triggered interrupt.
Type *)
This type is dependent on the selected mode of the module
Type **)
This type is dependent on the external switch (ASIC-Pins). It can be ET/F or ET/R or LT, depending
on the external connection. Parameterization must be done depending on the request of the applica-
tion about the Host-ICU (see chapter 2.3.2.17).
Information:
The IRQ interrupt output of ARM-ICU (ICUIRQ_O) is inverted and connected to the inter-
rupt input (nIRQ) of ARM926EJ-S.
2.3.2.14.1
Interrupts for accesses to missing addresses
The QVZ units detect any access to missing addresses and generate a pulse with dura-
tion Tp = 2/125 MHz. This pulse must be processed in the Interrupt Controller as an
edge-triggered interrupt.
2.3.2.14.2
Confirmation delay in the Memory Controller (EMC) address area
