REGISTERS
Command Byte
During a write transmission, the address byte is followed
by the command byte. The command byte determines which
of the following registers will be written or read.

Registers 0 and 1: Input Port Registers
These registers are inputonly. They reflect the incoming
logic levels of the pins, regardless of whether the pin is
defined as an input or an output by Registers 6 or 7. Writes
to these registers have no effect.
The externallyapplied logic level determines the default
value ‘X’.

Registers 2 and 3: Output Port Registers
These registers are outputonly. They reflect the outgoing
logic levels of the pins defined as outputs by Registers 6 and
7. Bit values in these registers have no effect on pins defined
as inputs. In turn, reads from these registers reflect the values
that are in the flipflops controlling the output selection, not
the actual pin values.
