Programming Model
7.3.1
Register file configuration
The AVR32B architecture specifies that the exception contexts may have a different number of
shadowed registers in different implementations. Figure 7-3 on page 22 shows the model used
in AVR32 AP.
Figure 7-3.
The AVR32 AP Register File
7.3.2
Status register configuration
The Status Register (SR) is splitted into two halfwords, one upper and one lower, see Figure 7-4
on page 22 and Figure 7-5 on page 23. 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.
