Recently, I'm writing the SWT driver of MPC5748G. But I got a probem when I unlock watchdog. The code is as follows.
/* unlock watchdog */
SWT_1_SR = 0xC520;
SWT_1_SR = 0xD928;
When i run "SWT_1_SR = 0xC520", there will be " No source available for " " ". So I can't debug my code step by step. How could i do. I would be very grateful if any one can help me.
