Register File Configuration

The AVR32UC register file is shown below.

4.4.2

Status Register Configuration

The Status Register (SR) is split into two halfwords, one upper and one lower, see

Figure 4-4

and

Figure 4-5

. 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 proces-
sor executes in. Refer to the AVR32 Architecture Manual for details.
