1.	What is the address range of SFRs?(a) 80h to feh(b) 00h to ffh(c) 80h to ffh(d) 70h to 80hI have been asked this question at a job interview.Enquiry is from Microcontroller (8051) in division Prototyping Embedded Devices of IOT
Answer» Right option is (c) 80h to ffh The explanation is: In 8051 there certain REGISTERS which uses the RAM addresses from80h to ffh. These are called as Special Function Registers. Some of the SRFrs are I/o ports and CONTROL operations as TCON, SCON, PCON.
