LINSCI serial communication interface (LIN master only)
Note:
206/324
The SCLK pin works in conjunction with the TDO pin. When the SCI transmitter is disabled
(TE and RE = 0), the SCLK and TDO pins go into high impedance state.
The LBCL, CPOL and CPHA bits have to be selected before enabling the transmitter to
ensure that the clock pulses function correctly. These bits should not be changed while the
transmitter is enabled.
