Register 0 and 1: Input port 0 and 1 registers (input-only port).
It reflects the incoming logic levels of the pins, regardless of whether the pin
is defined as an input or an output. Writes to this register have no effect.
The default value ‘X’ is determined by the externally applied logic level.

Default X X X X X X X X
Register 2 and 3: Output port 0 and 1 registers (output-only port).
It reflects the outgoing logic levels of the pins defined as outputs. Bit values
in this register have no effect on pins defined as inputs.

Register 4 and 5: Polarity inversion port 0 and 1 registers.
This register allows the user to invert the polarity of the Input port register
data. If a bit in this register is written with ‘1’, the Input port data polarity is
inverted. If a bit in this register is written with ‘0’, the Input port data polarity
is retained.

Register 6 and 7: Configuration port 0 and 1 registers.
This register configures the directions of the I/O pins. If a bit in this register
is written with ‘1’, the corresponding pin is enabled as an input. If a bit in this
register is written with ‘0’, the corresponding pin is enabled as an output. At
reset, the device’s ports are inputs.

Digital I/O Connectors (CN1~CN4)
CN1~CN4 are JST B10B-PHD-S-S, 2x5-pin P=2.0mm Dip connectors for
digital I/O interface that meet requirements for a system customary
automation control. These digital I/O signals are from two 16-bit PCA9535
and controlled through SMBus:
First group (CN1 and CN2), SMBus address: 0x40.
Second group (CN3 and CN4), SMBus address: 0x44.
CN1/CN2/CN3/CN4:
ZIO Expansion Connector (CN5)
The CN5 is for connecting ZIO module to CPU board.
