BREAK
Depending on the mode (LIN or UART), LCONF[1..0] bits of the LINCR register set the con-
troller in the following configuration
Table 15-3.
The LIN configuration is independent of the programmed LIN protocol.
The listening mode connects the internal Tx LIN and the internal Rx LIN together. In this
mode, the TXLIN output pin is disabled and the RXLIN input pin is always enabled. The same
scheme is available in UART mode.
Figure 15-6. Listening Mode
LBUSY bit flag in LINSIR register is the image of the BUSY signal. It is set and cleared by
hardware. It signals that the controller is busy with LIN or UART communication.
