Pin SPLIT provides a DC stabilized voltage of 0.5V
only. Pin SPLIT is floating in CAN Lowpower and Off modes. The V
used to stabilize the recessive common-mode voltage by connecting pin SPLIT to the
center tap of the split termination (see
A transceiver in the network that is not supplied and that generates a significant leakage
current from the bus lines to ground, can result in a recessive bus voltage of < 0.5V
this event, the split circuit will stabilize the recessive voltage at 0.5V
transmission will not generate a step in the common-mode signal which would lead to
poor ElectroMagnetic Emission (EME) performance.
A TXDC dominant time-out timer is started when pin TXDC is forced LOW. If the LOW
state on pin TXDC persists for longer than the TXDC dominant time-out time (t
the transmitter will be disabled, releasing the bus lines to recessive state. This function
prevents a hardware and/or software application failure from driving the bus lines to a
permanent dominant state (blocking all network communications). The TXDC dominant
time-out timer is reset when pin TXDC goes HIGH. The TXDC dominant time-out time
also defines the minimum possible bit rate of 10 kbit/s.
Pin TXDC has an internal pull-up towards V
pin is left floating.
The SBC provides 2 local wake-up pins (WAKE1 and WAKE2). The edge sensitivity
(falling, rising or both) of the wake-up pins can be configured independently via the WIC1
and WIC2 bits in the Int_Control register
wake-up via the wake-up pins. When wake-up is enabled, a valid wake-up event on either
of these pins will cause a wake-up interrupt to be generated in Standby mode or Normal
