Section 2 Programming Model
2.7 Processor Modes
There are two processor modes: user mode and privileged 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 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. There are certain registers and bits which
can only be accessed in privileged mode.
