#96190 - function of 8051 pins |
hello peoples,
some of question arises in my mind, as i am beginer in this arena. 8051 have 40 pins,but some pins have alternative use, plz tell me 1)how you use the pins for alternative function, like P0 for input/out put instread of address bit in case of external RAM. 2)P3 have rxd /txd, so how can i tell that i should use for TXD/RXD instead of basic input/output functions. 3)As i receive the data in SBUF and then bring it ACCUMULATOR, then if i want to send the same data to serial, what should i do. THANKS WITH REGARDS RAHIL ASLAM |
