By default we don't allow unaligned <mem> specifications in the config file.
Though for a machine like 'Victor HC-95A' is it useful to model it with combinations of unaligned devices. So we do allow it for a select few devices: devices that promise to not call any of the 'fillDeviceXXXCache()' methods.

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for reading means the data may be read directly from the buffer, thus bypassing the readMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Read a byte from a given IO port.
Reading via this method has no side effects (doesn't change the device status). If safe reading is not possible this method returns 0xFF. This method is not used by the emulation. It can however be used by a debugger. The default implementation just returns 0xFF.
