Table 8. Receive Output Bus Signal Map
When a serial address is received and a match is detected, the
address, and all data following that address, is passed to the
Receive FIFO (except in discard policy 3 where the address is
discarded). This continues until a serial address is received
that does not match the contents of the Address Register,
whereupon writes to the Receive FIFO are inhibited.The Serial
Address Register has a power-up default state where the
multicast field set to an all ones condition (FFh or 3FFh). When
set to this value the receiver accepts all data, regardless of the
presence or content of any received serial address. This
“promiscuous” address can also be forced by the momentary
assertion of the RESET*[1:0] pair.
The Serial Address Register is only used when the receiver is
operated with the Receive FIFO enabled (FIFOBYP* is HIGH)
and in operating modes where the discard policy is not 0 (see
Table 7
Serial Address Register Access
The Serial Address Register is accessed through the RXDATA
bus. Both reads and writes to the register require the device to
be addressed (AM* is LOW) and for RXRST* to be asserted
(LOW).

Receive Decoder Mode
When accessed for write or read operations, the RXRVS
signal is used as a read/write selector, and RXSC/D* is used
to select the operating mode (multicast or unicast) of the Serial
Address Register.
