Exception entry and exit summary
Return instruction
Exceptions arise whenever the normal flow of a program has to be halted temporarily,
for example, to service an interrupt from a peripheral. Before attempting to handle an
exception, the ARM7TDMI processor preserves the current processor state so that the
original program can resume when the handler routine has finished.
If two or more exceptions arise simultaneously, the exceptions are dealt with in the fixed
order given in Table 2-3.
This section provides details of the ARM7TDMI processor exception handling:

Table 2-3 summarizes the PC value preserved in the relevant r14 on exception entry, and
the recommended instruction for exiting the exception handler.
