2.5.2
There are two processor modes: privileged mode and user mode. The processor mode is
determined by the processor mode bit (MD) in the status register (SR). User mode is selected
when the MD bit is 0, and privileged mode when the MD bit is 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.

Note: * The hardware standby mode is entered when the CA pin goes low from any state.
