I have tried to implement some of the code posted for MPC5604P, but not work. Then I tried to configure only the recieve interruption, but still not working.
I´m using new codeWarrior, version 10.5.
This is my last code:
#include "MPC5604P.h"
#include "IntcInterrupts.h"
int counterTX = 0;
int counterRX = 0;
char receiveBuffer[20];
