Key Concepts and Implementation Details for 8051 Microcontrollers
Special Functon Register and Bit Declarations
The sfr and sbit keywords are used for declarations in 8051 microcontroller programming. sfr declares an entire special function register, while sbit declares a single bit within a register.
sfr output_port = 0xA0;
sbit indicator_bit = output_port ^ 3;
The #define preprocessor directive is also use ...
