Websbit sbit With typical 8051 applications, it is often necessary to access individual bits within an SFR. The C51 compiler makes this possible with the sbit data type. The sbit data type allows you to access bit-addressable SFRs. For example: sbit EA = 0xAF; This declaration defines EA to be the SFR bit at address 0xAF .
