BIT Assembler Statement

Arguments	symbol BIT address
Description	The BIT statement assigns an address (in the range 20h-2Fh or an 8051 bit-addressable SFR) to the specified symbol. The symbol may not be redefined. In addition, the BIT statement may create a bit name for the following bit-addressable items: Absolute addresses from 20H.0-2FH.7. For example, 23H.2. SFR bits which are in the bit-addressable space. For example, P3.3, or PSW.7. This creates an absolute bit because SFR symbols are absolute. Bits based on bytes contained in bit-addressable data sections. This results in relocatable bits if the bit-addressable data section is relocatable.
