WebJul 1, 2024 · Generally, whenever a byte has been received the 8051 will set the “RI” (Receive Interrupt) flag. This lets the program know that a byte has been received and that it needs to be processed. However, when SM2 is set the “RI” flag will only be triggered if the 9th bit received was a “1”. WebTable No.1 Features of 8051[3] 1.2.2 Registers: Registers are used to store information temporarily. The vast majority of 8051 registers are 8-bit registers. With an 8 bit data type, any data larger than 8 bits must be broken into 8-bits chunks before it is processed. Commonly used registers of the 8051 are A(accumulator), B, R0,
