Project Info
Cutted off from unknown TV main board. In this uC some kind of protection preventing further programming can be used, no tested yet as I don't have MOTOROLA programmer.
MOTOROLA FLASH protection bits
Programming interface for this uC is rather simple but I wasn't interested in MOTOROLA chips previously, from years it is in not realized plans.
It was rather common for manufactures to set protection bits. But it seems that some unblocking procedure is also possible:
MOTOROLA unblocking
Totally I have 4 modules with MC68HC908JL8, MC68HC908JK chips for experimets:
