sbit variables may not be declared inside a function.Refer to Bit-addressable Objects for more Individual bits of variables declared with the bdata memory The sbit data type declaration may be used to access Special function bits represent an independent declarationД¬lass that may not be interchangeable with other bit declarations So, to access bit 6 in the SFR at 0xC8, the SFR bit ToД¬alculate an SFR bit address, add the bit position to the SFR byteДЄddress. For example, SFRs at 0xA8 andД xD0 are bit-addressable, whereas SFRs at 0xC7 and 0ењЋB are not. Is evenly divisible by 8 are bit-addressable. It provides us many functions on single chip.

It have on chip one serial and four peripheral ports, 4K bytes of ROM, 128 bytes of RAM, counters, timers. 8051 microcontroller was first designed by Intel since 1980. The bit-position (which must be a number fromД -7) follows the carat symbol ('^') and specifies the bit position toДЄ character constant ( sbit-address) specifies This is a introduction of series of 8051 microcontroller tutorials. The bit-position (which must be a number from 0-7)ДЇollows the carat symbol ('^') and specifies the bit position toДЄ character constant ( sfr-address) specifies The previously declared SFR ( sfr-name) is theД«ase address for the sbit. TheД®xpression to the right of the equal sign ('=') specifies an absoluteД«it address for the symbolic name. To access bits within standard data types.ДЄny symbolic name can be used in an sbit declaration. Storage of objects accessed using sbit is assumed to be On the 8051, this is the enable all bit in the This declaration defines EA as the SFR bit at addressД xAF. To bit-addressable SFRs and other bit-addressable objects. With typical 8051 applications, it is often necessary to access Is the position of the bit within the SFR. The sbit type defines a bit within a special function
