correctly. If the TLB handler does not operate correctly, the emulator is hanged up.
In the E10A emulator, the MMU setting state is not changed during user program break.
Therefore, when the MMU is on in the user program, it is still on after user program break.
In SH7729 E10A emulator, note that the operation will be as follows if there is an access that
generates the TLB exception during break:
DMA cycle
I/O break
when the AUD pins are not connected to the emulator.
