/* The switch ADDR[4:1] configuration pins define the chip SMI device address
 * (ADDR[0] is always zero, thus only even SMI addresses can be strapped).
 *
 * When ADDR is all zero, the chip uses Single-chip Addressing Mode, assuming it
 * is the only device connected to the SMI master. In this mode it responds to
 * all 32 possible SMI addresses, and thus maps directly the internal devices.
 *
 * When ADDR is non-zero, the chip uses Multi-chip Addressing Mode, allowing
 * multiple devices to share the SMI interface. In this mode it responds to only
 * 2 registers, used to indirectly access the internal SMI devices.
