Other SFRs

The chart above is a summary of all the SFRs that exist in a standard 8051. All derivative microcontrollers of the 8051 must support these basic SFRs in order to maintain compatibility with the underlying MSCS51 standard.

A common practice when semiconductor firms wish to develop a new 8051 derivative is to add additional SFRs to support new functions that exist in the new chip.
