2.2.1.1
Registers D0–D7 are used as data registers for bit, byte (8-bit), word (16-bit), and longword (32-bit)
operations. They may also be used as index registers.
2.2.1.2
The address registers (A0–A6) can be used as software stack pointers, index registers, or base address
registers and may be used for word and longword operations.
2.2.1.3
The processor core supports a single hardware stack pointer (A7) used during stacking for subroutine calls,
returns, and exception handling. The stack pointer is implicitly referenced by certain operations and can
be explicitly referenced by any instruction specifying an address register. The initial value of A7 is loaded
