I am tring to update the mcu of our project from mc9s12xet256 to mpc5744P. now i have some questions about MPC5744P.
1 When i use multilink to load 5744p program, will the reset pin change?（because i am also using MC33FS6523, if the MC33FS6523 is not in debug mode, the power of 5744p will be off(3.3V and 5V, in less than 1 second) when i use multilink to load 5744p program, i guess it is because the reset pin changed . if the MC33FS6523 is in debug mode, everything is ok）
2 If i want to use bootloader (through can communication) ,there are three pins connected to this function. FAB, ABS, ABS , does that mean i can only use these pins as input? if i use these pins as output does that mean i can't use the bootloader function? is there any example about the bootloader(through can communication) of 5744p.
Sorry for my poor english, i can't get through this just by 5744p user manual.
