System Registers (Continued)
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
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
