SR- Status Register
EVBA - Exception Vector Base Address
ACBA - Application Call Base Address
CPUCR - CPU Control Register
Table 2-2.
The Status Register is mapped into the system register space. This allows it to be loaded into
the register file to be modified, or to be stored to memory. The Status Register is described in
detail in
This register contains a pointer to the exception routines. All exception routines start at this
address, or at a defined offset relative to the address. Special alignment requirements may
apply for EVBA, depending on the implementation of the interrupt controller. Exceptions are
described in detail in the AVR32 Architecture Manual.
Pointer to the start of a table of function pointers. Subroutines can thereby be called by the com-
pact acall instruction. This facilitates efficient reuse of code. Keeping this pointer as a register
facilitates multiple function pointer tables. ACBA is a full 32 bit register, but the lowest two bits
should be written to zero, making ACBA word aligned. Failing to do so may result in erroneous
behaviour.
Register controlling the configuration and behaviour of the CPU. The following fields are defined:

Description
Unused. Read as 0. Should be written as 0.
If set, COUNT is not set on COMPARE match. If cleared, COUNT is
cleared on COMPARE match.
Local Bus Enable. Must be written to 1 to enable the local bus. Any
access attempted to the LOCAL section when this bit is cleared will
result in a BUS ERROR.
