Address Space
Overview
Register File
PS017610-0404
The eZ8 CPU can access three distinct address spaces:
•
•
•
These three address spaces are covered briefly in the following subsections. For more
detailed information regarding the eZ8 CPU and its address space, refer to the eZ8 CPU
User Manual available for download at www.zilog.com.
The Register File address space in the Z8 Encore!
is composed of two sections—control registers and general-purpose registers. When
instructions are executed, registers are read from when defined as sources and written to
when defined as destinations. The architecture of the eZ8 CPU allows all general-purpose
registers to function as accumulators, address pointers, index registers, stack areas, or
scratch pad memory.
The upper 256 bytes of the 4KB Register File address space are reserved for control of the
eZ8 CPU, the on-chip peripherals, and the I/O ports. These registers are located at
addresses from
section are reserved (unavailable). Reading from an reserved Register File addresses
returns an undefined value. Writing to reserved Register File addresses is not recom-
mended and can produce unpredictable results.
The on-chip RAM always begins at address 000H in the Register File address space. The
Z8F640x family products contain 2KB to 4KB of on-chip RAM depending upon the
device. Reading from Register File addresses outside the available RAM addresses (and
not within in the control register address space) returns an undefined value. Writing to
these Register File addresses produces no effect. Refer to the Part Selection Guide sec-
tion of the Introduction chapter to determine the amount of RAM available for the spe-
cific Z8F640x family device.
The Register File contains addresses for the general-purpose registers and the eZ8
CPU, peripheral, and general-purpose I/O port control registers.
The Program Memory contains addresses for all memory locations having executable
code and/or data.
The Data Memory contains addresses for all memory locations that hold data only.
