40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT
OE is LOW (with OEPOL = 0) or HIGH (with OEPOL = 1) to observe a change in the outputs.
OCH = 0. When OCH = 1, the change in the port happens at the acknowledge phase.
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 the STOP command when OCH = 0, or at each acknowledge when OCH = 1.

The programing becomes effective at the Acknowledge.
Less than 5 bytes can be programmed by using the same 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, the sixth
Mask interrupt register will roll over to the first addressed Mask interrupt register.
