ARM Instruction Set Overview
To return after handling the exception, the SPSR is moved to the CPSR, and R14 is moved to
the PC. This can be done in two ways:
The ARM instruction set is divided into:
ARM instructions can be executed conditionally. Every instruction contains a 4-bit condition
code field (bit[31:28]).
