FIGURE 6:
8-BIT MODE: ADDRESS POINTER ENABLED (MCP23008 EXAMPLE)
When the address pointer is ENABLED and the device is in
8-bit mode, the address pointer will increment after every
byte is clocked. The address pointer will roll over to 00h
after exceeding 1Ah (which is the last location of Port B).

16-BIT MODE: ADDRESS POINTER DISABLED (MCP23017 EXAMPLE)
When the address pointer is DISABLED and the device is in
16-bit mode, the address pointer will alternate between the
register pair. Also, the initial address can be either register
address (e.g., 14h or 15h) and the pointer will still alternate
between the registers.
