8051 Micro controller
Upon reset all port pins and port registers are high.
I follow these instructions...
P0=0x00;
P0=0xFF;
Now ,the result is - All P0 registers are high & all P0
pins are low.
Q1) Does this low P0 pins indicate high impedance floating
load in the case of P0?
Now, I start the program with the following instruction only.
P0=0xFF;
But All P0 registers and pins remain high.
Q2)What is the difference here? What's happen
