The TSS463B is a microprocessor controlled line controller for the VAN bus. It can inter-
face to virtually any microprocessor that includes SPI or SCI interface.

The circuit also features a single interrupt pin. This pin can be treated as level sensitive,
i.e. if there is a pending interrupt inside the circuit when another interrupt is reset the INT
pin will emit a high pulse with the same pulse width as the internal write strobe (typically
20 ns).

The TSS463B provides one full Motorola© compatible SPI interface.
It includes one full compatible Intel
One 9-bits SCI interface is also integrated.

2. Leaving MISO output pin floating in high impedance mode slightly increases standby
or the µC RESET pin or unconnected (inactive with internal pull-up).
