Register File Configuration
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
and
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.
