It allows access to single bits of SFR (special function registers). Some of SFRs are bit addressable. We can use sbit to access individual bits of the port. As we have accessed P1.0 Pin by name LED. void Delay() { int i=0,j=0; for(i=0;i<100;i++) {
WebJun 13, 2024 · By default, the output of ports of 8051 is a HIGH pulse. If we consider port 0, we can say that by default, P0 = 0xFF is set. When the switch is in open state pin P0.1 (to which the switch is connected) is directly connected to the +5V power supply through a pull-up resistor, but as soon as the switch is turned ON (pressed), the circuit is complete, and … WebAnswer to Solved = = = #include unsigned int x; sbit P10 = P1^0; sbit
WebDeclaring statement is sbit button=P1^0; Port 1 pin 1 is declared as led, means i am connecting my led to this pin of microcontroller.
