The bus collision detection function can be used if UART0 is enabled for transmission (TE bit in U0C1 register
= 1). To detect a bus collision during Synch Break transmission, set the BCE bit in the LINCR2 register to 1
(bus collision detection enabled).
Figure 27.9 shows an Operating Example When Bus Collision is Detected.
