what is the difference between sending high to a pin or making a bit of a port as input using setb command ? i always see same command and different comment... That's the trouble with sloppy terminology! Unlike some other architectures, In the standard 8051, there is no way to "make a port an output" nor to "make a port an input" - they are all bidirectional[1] all the time: See: http://www.8052.com/forum/read.phtml?id=88984 If the datasheet doesn't say anything different from the "bible," then the "bible" applies. [1] Actually, they's quasi-bidirectional |
