The Status Register
Figure 2-1.
The Status Register (SR) consists of two halfwords, one upper and one lower, see
page 8
well as the L and T bits, while the upper halfword contains information about the mode and state
the processor executes in. The upper halfword can only be accessed from a privileged mode.
