LIN (LOCAL INTERCONNECT NETWORK) SOLUTIONS

The corresponding initialization code is:

Interrupt:

The timer is only used for the timeout handling so the “LINTimeOut_Interrupt” function just

needs to be called in the Timer A interrupt service routine defined by the application which cor-

responds to the following code:

TACR1=0x40;

TACR2=0x00;

TASR;

TAOC2_L;

TAOC2_H=0x55;

TASR;

TAOC1_L;

TAOC1_H=0x55;

/* -output compare interrupt enabled */

/* prescaler = 4 */

/* erase OC2F flag and */

/* and disable it

/* erase OC1F flag and */

/* and disable it
