A2 is the hardware selectable pin, A1 and A0 are software selectable pins.
A system could have up to two PCF8598C-2 devices on the same I
to a 16 kbit EEPROM, or 2 devices of 1024 bytes of memory, or 8 pages of 256 bytes
of memory.
A1 and A0 select a 256 byte page (one of the four pages available) on the selected
device. The device is selected by bit A2.
