HV Configuration
Following is a code example to enable LIN.
char HVstatus;
It is best practice to implement the high voltage communication routine in a function and call this function throughout the code.
do{
}
while (!(HVstatus & 0x4));
HVDAT = 0x01;
HVCON = 0x08;
do{
}
while(HVstatus & 0x1);
HVstatus = HVCON;
