2.1.4
In comparison to the H8/300H CPU, the H8S/2000 CPU has the following enhancements.
2.2
The H8S/2357 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.
2.2.1
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.
Additional control register
Enhanced instructions
Higher speed
One 8-bit control register has been added.
Addressing modes of bit-manipulation instructions have been enhanced.
Two-bit shift instructions have been added.
Instructions for saving and restoring multiple registers have been added.
A test and set instruction has been added.
Basic instructions execute twice as fast.
