Microcontroller › 8051 › registors in 8051
what is the function of SFR in microcontrollers………………
please tell me
SFR are special function registers which have predefined roles and addresses. For example the register at address 0x80 in AT89C51 is allocated to port 0. So whatever you write on this address/register will be given at port 0. Similary there are many more SFR. The details can be found in the datasheet.
