please could you help me with this as it is a newbie section
I have a stereo with a 68HC11E9 inside I have a programmer to read this without desoldering. (in circuit programming) So i can get the dump. Im very new to working with MCU. The problem i have is that there are so many pins on the mcu i do not know which ones i need to connect to, so i can read it. I have googled for hours and hours and done lots of research, but cant find any info about which pins on the mcu i need to connect to.
Im ok at reading the 25xx 24xx 93xx eeproms as these are simple to read with just connecting the IC clip to the 8 pin smd.
It would be greatly apreciated if someone could help me .
