Status Register Configuration
The Status Register (SR) is split into two halfwords, one upper and one lower, see Figure 4-4 on
page 26 and Figure 4-5 on page 27. The lower word contains the C, Z, N, V, and Q condition
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.
