x = unknown, - = unimplemented locations read as ‘0’. Shaded cells are not used for asynchronous reception.
This bit is only implemented on the PIC16F88. The bit will read ‘0’ on the PIC16F87.

This timing diagram shows a data byte followed by an address byte. The data byte is not read into the RCREG (Receive Buffer)
because ADDEN = 1.
This timing diagram shows a data byte followed by an address byte. The data byte is not read into the RCREG (Receive Buffer)
because ADDEN was not updated and still = 0.
