hi,

Are you sure that when LB2 is programmed, it will run from internal memory regardless of /EA setting?
This is what datasheet says about protect mode 4. But I do check it never because all projects I did have /EA tied to Vcc. From other side it seems so, because only at mode 4 OP has problems - seems MCU does internal fetches at this mode. Regards, Oleg |
