Status Register Configuration
The AVR32UC register file is shown below.
Figure 4-3.
The Status Register (SR) is split into two halfwords, one upper and one lower, see
page 25
code flags and the R, T, and L bits, while the upper halfword contains information about the
mode and state the processor executes in. Refer to the AVR32 Architecture Manual for details.
