AT697F ADVANCE INFORMATION

123

7703C–AERO–6/09

Break on error traps

If set, will force the processor into debug mode on all except the following traps: priviledged_instruction,

fpu_disabled, window_overflow, window_underflow, asynchronous_interrupt, ticc_trap.

Break on trap

If set, will force the processor into debug mode when any trap occurs.

Break on DSU breakpoint

If set, will force the processor to debug mode when an DSU breakpoint is hit.

Break now

Force processor into debug mode. If cleared, the processor will resume execution.

Break on S/W breakpoint

If set, debug mode will be forced when an breakpoint instruction (ta 1) is executed

Break on IU watchpoint

If set, debug mode will be forced on a IU watchpoint (trap 0xb).

Break on error

if set, will force the processor to debug mode when the processor would have entered error condition (trap in

trap).

Freeze timers

If set, the scaler in the LEON timer unit will be stopped during debug mode to preserve the time for the software

application.

Break on trace

If set, will generate a DSU break condition on trace freeze.

Delay counter mode

In mixed tracing mode, setting this bit will cause the delay counter to decrement on AHB traces. If reset, the

delay counter will decrement on instruction traces

Trace enable.

Enables the trace buffer.
