OE is LOW to observe a change in the outputs.
Two, three, or four adjacent banks can be programmed by using the Auto-Increment feature (AI = 1) and change at the corresponding output port becomes effective at
each acknowledge.

The programming becomes effective at the acknowledge.
Less than 5 bytes can be programmed by using this scheme. D5, D4, D3, D2, D1, D0 refers to the first register to be programmed.
If more than 5 bytes are written, previous data are overwritten (the sixth Configuration register will roll over to the first addressed Configuration register, the sixth Polarity
Inversion register will roll over to the first addressed Polarity Inversion register and the sixth Mask Interrupt register will roll over to the first addressed Mask Interrupt
register).
