6.1 Registers
6.1.1 Command byte
The command byte is the first byte to follow the address byte during a write transmission.
It is used as a pointer to determine which of the following registers will be written or read.
6.1.2 Register 0 - Input Port register
This register is a read-only port. It reflects the incoming logic levels of the pins, regardless
of whether the pin is defined as an input or an output by Register 3. Writes to this register
have no effect.
The default ‘X’ is determined by the externally applied logic level, normally logic 1 when
no external signal externally applied because of the internal pull-up resistors.
