I have a problem with In Circuit Programming of a MC908LJ24. I have connected a 32 kHz external crystal to the MCU, and I'm able to enter monitor mode and program the Flash, except for the vector table. Moreover, the mass erase operation performed through the internal ROM functions doesn't work. I enter monitor mode without VHI, as the device has vectors blank.
Any ideas?
