Web8051 has an interrupt system which can handle internal as well as external interrupts with priority. WebSpecial function registers are upper RAM in the 8051 microcontrollers. These registers contain all peripherally related registers like P0, P1, P2, P3, timers or counters, serial port, and interrupts-related registers. The SFR memory address starts from 80h to FFh. The SFR register is implemented by bit-address registers and byte-address registers.
