3.3.1 Accumulator
3.3.2 Index Register
3.3.3 Stack Pointer
MC68HC05P18A
MOTOROLA
The accumulator (A) is a general-purpose 8-bit register. The CPU uses
the accumulator to hold operands and results of arithmetic and non-
arithmetic operations.
In the indexed addressing modes, the CPU uses the byte in the index
register (X) to determine the conditional address of the operand.
The 8-bit index register can also serve as a temporary data storage
location.
The stack pointer (SP) is a 16-bit register that contains the address of
the next location on the stack. During a reset or after the reset stack
pointer (RSP) instruction, the stack pointer is preset to $00FF. The
address in the stack pointer decrements as data is pushed onto the
stack and increments as data is pulled from the stack.
