Section 1 CPU
Note: * The maximum operating frequency and instruction execution time differ depending on
1.1.2
Differences between the H8S/2600 CPU and the H8S/2000 CPU are as follows.
In addition, there may be defferences in address spaces, EXR register functions, power-down
states, and so on. For details, refer to the relevant microcontroller hardware manual.
