40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT
The programming becomes effective at the Acknowledge.
If more than 1 byte is written, previous data is overwritten.

10 for mode selection register programming
If AI = 0, the same register is read during the whole sequence.
If AI = 1, the register value is incremented after each read. When the last register bank is read, it rolls over to the first byte of the
category (see category definition in Section 7.3 “Command register”).
The INT signal is released only when the last register containing an input that changed has been read. For example, when
IO2_4 and IO4_7 change at the same time and an Input Port register read sequence is initiated, starting with IP0, INT is
released after IP4 is read (and not after IP2 is read).
