Reset / Abort Sources
3.1
Reset / Abort Sources
The device Resets and Aborts are handled as shown in the following table. The table shows the source of
the error, the system mode, the type of error response and the corresponding Error Signaling Module
(ESM) channel. Only standard ARM exception handlers and ESM errors are used.

(1)
The Undefined Instruction TRAP is NOT detectable outside the CPU. The trap is taken only if the Code reaches the execute stage of
the CPU.
