SYStem.CPU Operation mode

This option specifies operation mode of the cpu, which is normally defined with the MD0..2 pins of the cpu.

But, the values of this pins in the target are not responsible for the operation mode, so that the pin levels can

differ from the emulator setting.

This option must be set corresponding to the EAE bit in the BCRL register of the cpu. The emulator needs

this information to set the breakpoints correctly.
