2.1.1
The differences between the H8S/2600 CPU and the H8S/2000 CPU are as shown below.
• Register configuration
• Basic instructions
• The number of execution states of the MULXU and MULXS instructions
In addition, there are differences in address space, CCR and EXR register functions, power-down
modes, etc., depending on the model.
