Low-voltage 16-bit I2C-bus I/O port with interrupt  
6.2.2 Input port register pair (00h, 01h)  
The Input port registers (registers 0 and 1) reflect the incoming logic levels of the pins,  
regardless of whether the pin is defined as an input or an output by the Configuration  
register. The Input port registers are read only; writes to these registers have no effect.  
The default value ‘X’ is determined by the externally applied logic level. An Input port  
register read operation is performed as described in Section 7.2 “Reading the port  
registers”.

6.2.3 Output port register pair (02h, 03h)  
The Output port registers (registers 2 and 3) show the outgoing logic levels of the pins  
defined as outputs by the Configuration register. Bit values in these registers have no  
effect on pins defined as inputs. In turn, reads from these registers reflect the value that  
was written to these registers, not the actual pin value. A register pair write is described in  
Section 7.1 and a register pair read is described in Section 7.2.
