Section 2 CPU
2.1.4
In comparison to the H8/300H CPU, the H8S/2600 CPU has the following enhancements.
• Additional control register
• Enhanced instructions
• Higher speed
2.2
The H8S/2600 CPU has two operating modes: normal and advanced. Normal mode * supports a
maximum 64-kbyte address space. 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.
Note: * Not available in the chip.
