Extended Communication Control Register (ECCR2/
ECCR3)
The extended communication control register provides bus idle recognition interrupt
settings, synchronous clock settings, and the LIN Synch break generation.
■
Extended Communication Control Register (ECCR2/ECCR3)
Figure 20.4-7 shows the bit configuration of the extended communication control registers (ECCR2/
ECCR3), and Table 20.4-6 shows the functions of each bit in the resisters.
