10.1.3 Validity flag input (VI)
Validity flags can be input from RX5/VI by switching the contents of RX5/VI input by VISEL.
The timing of writing a validity flag is shown below. The validity flag can be also written with the microcontroller
interface, but port settings have priority over the validity flag.
Writing validity flags with the microcontroller interface is done using VMODE.

10.1.4 User data input (UI)
User data can be input from RX6/UI by switching the contents of RX6/UI input by UISEL.
The timing of writing the user data is shown below.
