R1
RECEIVE BUFFER EMPTY: Status bit which indicates that the Receive Buffer does
not have any complete packets to read. (Read only.)

ACPT BAD
PKTS
RW0
ACCEPT BAD PACKETS: When set high, allows packets with CRC, and/or alignment
errors or packets that are short, to be saved into the Receive Buffer for analysis.
Otherwise such packets would be discarded automatically by the Receiver and
removed from the buffer.
4
RX SHORT
ADDR
RW0
RECEIVE SHORT ADDRESS: When set high, instead of customary 48-bit NODE ID
address filter, only first 40 bits of NODE ID are compared.
3
ACCPT
SHORT
PKTS
RW0
ACCEPT SHORT PACKETS: When set high, allows short packets (with less than 60
bytes, excluding Preamble and CRC, i.e. below IEEE minimum length) to be saved into
the Receive Buffer. Otherwise such packets would be discarded automatically by the
Receiver and removed from the buffer.

ADDRESS FILTER MODE: These two bits control the address filtering on incoming
packets. Note that self reception of broadcast and multicast packets is prohibited
except in Accept all packets and loopback modes. When LBC is low (loopback mode),
broadcast packets can be self-received, except in Reject All Packets mode.

NODE ID.
