Interrupt Sources For Arm-Fiq; High-Priority Interrupts For Debugging; Table 10: Host Intb, Interrupt Sources - Siemens ERTEC 200P-2 Manual

In the address area of the EMC, the XCE_PER(3:0) outputs become active and the
Memory Controller waits for the XRDY_PER input signal. The confirmation delay monitor-
ing activated in the Async Wait Cycle Config Register (see chap. 2.3.5.8) after
((MAX_EXT_WAIT + 1) x 16) AHB clock pulses creates an internal ready signal for the
Memory Controller and an IRQ. The IRQ will be removed when the QVZ monitoring is
disabled.

Interrupt sources for ARM-FIQ

The Interrupt contoller will have interrupts from the following function blocks:
IRQ Interrupt Name
no.
0 Default interrupt
1 FIQ_SEL_1
2 FIQ_SEL_2
3 FIQ_SEL_3
4 FIQ_SEL_4
5 FIQ_SEL_5
6 FIQ_SEL_6
7 FIQ_SEL_7
Type ***) This type is dependent on the Type of ARM-IRQ. It can be ET/F or ET/R or LT.
Information:
The FIQ interrupt output of ARM-ICU (CUFIQ_O) is inverted and connected to the inter-
rupt input (nFIQ) of ARM926EJ-S.

High-priority Interrupts for Debugging

As effective RT debugging, the interrupts of the embedded ICE RT communication chan-
nel (
COMMRX926, COMMTX926)
FIQ7. This allows interrupt routine debugging.
