VALIDITY FLAG INPUT (VI)
Validity flags can be input from RX5/VI by switching the RX5/VI input contents with VISEL.
The validity flag write timing is shown below. The validity flag can be written with the micro-controller
interface but port settings have priority.
Writing validity flags with the micro-controller interface is done using VMODE.
