With emulator (JTAG) connected, HPI access will work only if code is running. If you
are single-stepping or at a breakpoint, an HPI access will "bounce off".
If you run your test code in simple loop, then set the mem watch window to 0x1000,
then make HPI access to 0x1000 with loop code running, you will see the update (of
course that assumes your HPI interface is correct).
