* These are our custom controller functions for all IOPAGE accesses.
*
* Note that we try to have reasonable fall-backs for byte reads when only short read handlers exist,
* and short reads if only byte handlers exist. Ditto for writes. These fall-backs may not always be
* appropriate; for example, when a byte write falls back to a short write, the address must be read
* first, and depending on the underlying I/O device, that may or may not have side-effects. It's really
* up to the device to know whether that matters, and provide all the necessary handlers if it does.
*
* TODO: Another small potential improvement would be for addIOHandlers() to predefine fall-backs for all
* missing handlers, so there's never a need to check each entry (eg, afn[0], afn[1], etc) before calling
* it. However, since there's no avoiding checking afn itself (unless we FULLY populate the aIONotify
* array), and since these I/O accesses should be pretty infrequent relative to all other memory accesses,
* the benefit seems pretty minimal.
