This timing diagram shows a data byte followed by an address byte. The data byte is not read into the RCREG

This timing diagram shows an address byte followed by an data byte. The data byte is not read into the RCREG

Note
1:
This timing diagram shows an address byte followed by an data byte. The data byte is read into the RCREG
(Receive Buffer) because ADEN was updated after an address match, and was cleared to a ‘0’, so the contents of
the Receive Shift Register (RSR) are read into the Receive Buffer regardless of the value of Bit 8.
