FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Figure 20. CAN Interface Levels
TXD AND RXD PINS
The TXD pin has an internal pull-up to V2. The state of TXD depends on the V2 status. RXD is a push-pull structure, supplied
by V2. When V2 is set at 5.0 V and CAN is TXRX mode, RXD reports bus status. For details, refer to Table , page 28, Table 9,
The TXD pin is a push-pull structure between the V2 pin and GND. The circuitry has a parasitic diode between RXD and V2.
It is illustrated in Figure 25. This parasitic diode is reversed biased in normal operation (TXD voltage is lower or equal to V2). In
case the TXD voltage is greater than V2, a current will flow into the diode.
If the V2 pin is low (e.g. in sleep mode, or in stop with a ballast transistor), the current leakage at V2 is low enough (10
A
max) to ensure than the RXD pin can be pulled up by an external resistor (i.e. the MCU RXD pin internal pull-up).
The states of the RXD pin in the following Table 9 and 10 is dependant upon external circuitry connected to the V2 and RXD
pins.
CAN TXRX MODE AND SLEW RATE SELECTION
The slew rate selection is done via CAN register (refer to Tables 22 through 24 on page 50). Four slew rates are available and
control the recessive-to-dominant and dominant-to-recessive transitions. The delay time from TXD pin to CAN bus, from CAN
bus to RXD, and from the TXD to RXD loop time is affected by the slew rate selection.
