WebMay 6, 2013 · Push button switch is connected to the first bit of PORT 0 (P0.0) which is configured as an input pin. Which is connected to a pull up resistor as there is NO INTERNAL PULL UP RESISTORS FOR PORT P0. Thus P0.0 pin is at Vcc potential when the switch is not pressed. When the switch is pressed this pin P0.0 will be grounded. WebNov 14, 2011 · sbit-address is the address of the SFR bit. With typical 8051 applications, it is often necessary to access individual bits within an SFR. The sbit type provides access to bit-addressable SFRs and other bit-addressable objects. For example: sbit TestLed = P1^6; TestLed = name; P1 = SFR port1. 6 = bit position means Port1 6th bit. software nyk
