Figure 3.58 Address Translation according to VP_MAP Tables
How to translate addresses depends on the settings of the radio buttons of the memory area group
in the [Configuration] dialog box. The following shows how to translate addresses in each setting
state.
• When the Normal radio button is selected:
The VP_MAP table has a priority over the TLB. When the VP_MAP table is enabled and the
specified address is within the VP_MAP table settings, the emulator translates the address
according to the VP_MAP table. If the specified address is outside the VP_MAP table settings
even when the VP_MAP table is enabled, or when the VP_MAP table is disabled, the emulator
translates the address according to the MMU state.
• When the Virtual radio button is selected:
The address is translated according to the TLB. If the specified address is outside the TLB
table settings, a TLB error will occur.
• When the Physical radio button is selected:
The address is not translated.
