(Receive Buffer) because ADEN = 1 and Bit 8 = 0.
(receive buffer) because ADEN was not updated (still = 1) and Bit 8 = 0.
(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.
