Stack
Note:
The Z86D73 internal register file is used for the stack. An 8-bit Stack Pointer
(R255) is used for the internal stack that resides in the general-purpose registers
(R4–R239). SPH is used as a general-purpose register only when using internal
stacks.

When SPH is used as a general-purpose register and Port 0 is
in address mode, the contents of SPH are loaded into Port 0
whenever the internal stack is accessed
