#108965 - Solution Responding to: ???'s previous message |
I think, in this case, it will be a chort-soldering to pin 6 (P3.0/RxD) thiis pin is used during production via testprobe for RS232 communication, therefor it has a 4k7 pullupresistor to 5V. This pin isnt used after production tests. So now i only have to verify that RS232 connections dont disturb /EA pin while programing and testing.
Cant se any danger in this solution. / Kjell |
