Figure 2-1. Programming Model  
Accumulators A and B are general-purpose 8-bit accumulators used to  
hold operands and results of arithmetic calculations or data  
manipulations. Some instructions treat the combination of these two 8-  
bit accumulators as a 16-bit double accumulator (accumulator D).  
Index registers X and Y are used for indexed addressing mode. In the  
indexed addressing mode, the contents of a 16-bit index register are  
added to 5-bit, 9-bit, or 16-bit constants or the content of an accumulator  
to form the effective address of the operand to be used in the instruction.  
Stack pointer (SP) points to the last stack location used. The CPU12  
supports an automatic program stack that is used to save system  
context during subroutine calls and interrupts, and can also be used for  
temporary storage of data. The stack pointer can also be used in all  
indexed addressing modes.  
Program counter is a 16-bit register that holds the address of the next  
instruction to be executed. The program counter can be used in all  
indexed addressing modes except autoincrement/decrement.
