How to catch exceptions/interrupts using ULINK2

Hi.

I'm new to SAM7X and KEIL uV4 and are converting code from another IDE (written by another person). The SW seems to "fly away" due to some exception/interrupt I cannot detect. When I press RUN (F5) from the KEIL uV4 Debugger (using ULINK2), the SW executes OK for a while and then "suddely fly away". When I execute the uV4 STOP command after some 10th seconds, I see that CPSR=0x8000009B and the SCPSR=0x8000009B. I cannot find a good explaination in the KEIL uV4 manual:
Q1) How to continously see/monitor where the PC is (Register view is not refreshing)
Q2) How to catch/trace/see/detect any (unwanted) excception/interrupt occuring ?

I appreciate your comments.
