ERTEC 200P-2 Manual
Technical data subject to change
Version 1.0
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_EX 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.

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.
2.3.2.15.1 High-priority Interrupts for Debugging
As effective RT debugging, the interrupts of the embedded ICE RT communication chan-
nel (
COMMRX926, COMMTX926)
or the interrupt of UART2 can be mapped over FIQ1 to
FIQ7. This allows interrupt routine debugging.
