DESCRIPTION
7
RLD
INT EN
RW0
INTERRUPT ENABLE: When high, enables RLD, BMPR15<7>, to generate an interrupt.
6
LLD
INT EN
RW0
INTERRUPT ENABLE: When high, enables LLD, BMPR15<6>, to generate an interrupt.
5
RJAB
INT EN
RW0
INTERRUPT ENABLE: When high, enables RJAB, BMPR15<5>,, to generate an interrupt.

2
SKIP PKT
RW0
SKIP RECEIVED PACKET: When ‘1’ is written to this bit, flushes remainder of the current
received packet. Adjusts the system read pointer to the beginning of the next received
packet, if there is one, or to the end of the buffer if there is not.
1
INT EN
RW0
INTERRUPT ENABLE: When high, enables SQE, DLCR15<1>, to generate an interrupt.
0
FILTER
SELF RX
RW1
FILTER SELF RECEIVE: When set to 1, disables the accept all packets mode self receive
function. When set to 0, enables the self receive function in accept all packets mode.
TRANSCEIVER STATUS REGISTER
Table 26 describes the Transceiver Status Register, BMPR15.
Writing a ‘1’ to bits <7:3> and <1> of this register clears the
respective status condition. Writing ‘0’ to these bits has no ef-
fect.

DESCRIPTION
7
RLD
RC0/1
REMOTE LINKDOWN: When high and bit 4 is also high, indicates that remote 10BASE-T
port is in linkdown condition. Can generate interrupts if enabled by interrupt enable bit
BMPR14<7>.
6
LLD
RC0/1
LOCAL LINK DOWN: When high, indicates that local 10BASE-T port is in link down condi-
tion. Can generate interrupts if enabled by interrupt enable bit BMPR14<6>.
5
RJAB
RC0/1
REMOTE JABBER: When high and bit 4 is also high, indicates that remote 10BASE-T port
is in Jabber condition. Can generate interrupts if enabled by interrupt enable bit
BMPR14<5>.
4
RMT PORT
RC0/1
REMOTE SIGNALING: When high, indicates that the remote 10BASE-T port has remote
function signaling compatible with that of the MB86964. When this is the case, the RLD and
RJAB status is valid and is being continuously updated by the remote port. When this bit is
low, RLD, and RJAB are meaningless.
3
RXI POL
REV
RC0/1
RXI POLARITY REVERSAL: When high, indicates reversed polarity on the 10BASE-T re-
ceive line.
2
0
N0
RESERVED: Write 0.
1
SQE
RC0
SIGNAL QUALITY ERROR: When set to 1, indicates detection of SQE. Can generate
interrupts if enabled by interrupt enable bit BMPR14<1>.
0
0
N0
RESERVED: Write 0.
