Register File.
The register file (bank 0) consists of four I/O
port registers, 236 general-purpose registers, and 16 con-
trol and status registers (R0-R3, R4-R239, and R240-
R255, respectively), Plus two expanded registers groups
(Banks D and F). Instructions can access registers directly
or indirectly through an 8-bit address field. This allows a
short, 4-bit register address using the Register Pointer
(Figure 23). In the 4-bit mode, the register file is divided
into 16 working register groups, each occupying 16 contin-
uous locations. The Register Pointer addresses the start-
ing location of the active working register group.
Note:
Working register group E0-EF can only be access-
ed through working registers and indirect addressing
modes.
Stack.
The Z86L/CX2 external data memory or the inter-
nal register file is used for the stack. An 8-bit Stack Pointer
(R255) is used for the internal stack that resides in the gen-
eral-purpose registers (R4-R239). SPH is used as a gen-
eral-purpose register only when using internal stacks.
Note:
When SPH is used as a general-purpose register
and Port 0 is in address mode, the contents of SPH will be
loaded into Port 0 whenever the internal stack is accessed.
