Processing Modes
There are two processing modes: user mode and privileged mode. The processing mode is
determined by the processing mode bit (MD) in the status register (SR). User mode is selected
when the MD bit is cleared to 0, and privileged mode when the MD bit is set to 1. When the reset
state or exception state is entered, the MD bit is set to 1. When exception handling ends, the MD
bit is cleared to 0 and user mode is entered. There are certain registers and bits which can only be
accessed in privileged mode.
