11.1.3 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.

11.1.4 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.
It is also possible to write user data using the preamble B sync signal as the reference. Generation of the preamble B
sync signal is configured in PBSEL[1:0] as in the case of the DIR function. After the setting, the signal is output from
CKST/PB.
