Hi,

 

Can anyone elaborate more info on eeprom hardware interlock. When testing a batch of boards with MC9S12DJ128 using the same firmware, I encounted the following problem: after power reset, bit EPOPEN and EPDIS of EPROT was set to zero on some boards and cannot be initialized to 1, while others have such issue. 

 

thanks
