General-Purpose Registers
Register File Organization
Table 6. eZ8 CPU Control Registers
Other than the upper 256 registers reserved for control functions, all other available
addresses within the Register File are available for general-purpose use. Refer to the
device-specific Product Specification to determine the addresses available.
The Register File can be accessed as a 4096 byte linear address space using 12-bit address-
ing mode, as sixteen 256-byte Register Pages using 8-bit addressing mode, or as sixteen
16-byte Working Register Groups per Register Page using 4-bit addressing mode. Figure 3
illustrates the organization of the Register File. Attempts to read unavailable Register File
addresses return an undefined value. Attempts to write to unavailable Register File
addresses produce no effect.
