Default
Description
18.15
Reserved
0, RO
Reserved
:
Write as 0, ignore on read.
18.14
LP_EN
1, RW
Link Pulse Enable
:
1=Transmission of link pulses enabled.
0=Link pulses disabled, good link condition forced.
This bit is valid only in 10 Mbps operation.
18.13
HBE
Inverse Pin 94,
RW
Heartbeat Enable
:
1=Heartbeat function enabled.
0=Heartbeat function disabled.
When the NetPHY-1 device is configured for Full Duplex operation, this bit
will be ignored (the collision/heartbeat function is invalid in Full Duplex
mode). The initial state of this bit is the inverse value of RPTR/NODE input
pin at power on reset.
18.12

0, RO
Reserved
:
Write as 0, ignore on read.
18.11
JABEN
1, RW
Jabber Enable
:
1= Jabber function enabled.
0= Jabber function disabled.
Enables or disables the Jabber function when the NetPHY-1 device is in
10BASE-T Full Duplex or 10BASE-T Transceiver Loop-back mode.
18.10
10BT_SER
Pin 98, RW
10BASE-T Serial Mode
:
1=10BASE-T serial mode selected.
0=10BASE-T nibble mode selected.
The value on the 10BTSER input pin is latched into this bit at power-up/
rese.t
Serial mode not supported for 100 Mbps operation.
18.9-18.1

Reserved
:
Write as 0, ignore on read.
18.0
POLR
0, RO
Polarity Reversed
:
When this bit is set to 1, it indicates that the 10M cable polarity is reversed.
This bit is set and cleared by 10BASE-T module automatically.
