2.2 CPU Operating Modes
The H8S/2319 Group CPU has advanced operating mode. Advanced mode supports a maximum
16-Mbyte total address space (architecturally a maximum 16-Mbyte program area and a maximum
of 4 Gbytes for program and data areas combined). The mode is selected by the mode pins of the
microcontroller.
Advanced Mode
Address Space: Linear access is provided to a 16-Mbyte maximum address space (architecturally
a maximum 16-Mbyte program area and a maximum 4-Gbyte data area, with a maximum of 4
Gbytes for program and data areas combined).
Extended Registers (En): The extended registers (E0 to E7) can be used as 16-bit registers, or as
the upper 16-bit segments of 32-bit registers or address registers.
Instruction Set: All instructions and addressing modes can be used.
