8.10 10BASE-T Configuration/Status (10BTCSR) - 18

Bit

Bit Name

Default

Description

18.15

Reserved

0, RO

Reserved

Read as 0, ignore on write

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 10Mbps operation

18.13

HBE

1,RW

Heartbeat Enable

1 = Heartbeat function enabled

0 = Heartbeat function disabled

When the DM9161 is configured for full duplex operation, this bit will

be ignored (the collision/heartbeat function is invalid in full duplex

mode)

18.12

SQUELCH

1, RW

Squelch Enable

1 = Normal squelch

0 = Low squelch

18.11

JABEN

1, RW

Jabber Enable

Enables or disables the Jabber function when the DM9161 is in

10BASE-T full duplex or 10BASE-T transceiver loopback mode

1 = Jabber function enabled

0 = Jabber function disabled

18.10

10BT_SER

0,RW

10BASE-T GPSI Mode

1 = 10BASE-T GPSI mode selected

0 = 10BASE-T MII mode selected

GPSI mode is not supported for 100Mbps operation

18.9-18.1

Reserved

0, RO

Reserved

Read as 0, ignore on write

18.0

POLR

0, RO

Polarity Reversed

When this bit is set to 1, it indicates that the 10Mbps cable polarity is

reversed. This bit is automatically set and cleared by 10BASE-T

module

Bit

Bit Name

Default

Description

21.15

INTR PEND

0, RO

Interrupt Pending

Indicates that the interrupt is pending and is cleared by the current

read. This bit shows the same result as bit 0. (INTR Status)

21.11

FDX mask

1, RW

Full-duplex Interrupt Mask

When this bit is set, the Duplex status change will not generate the

interrupt

21.10

SPD mask

Speed Interrupt Mask

When this bit is set, the Speed status change will not generate the

interrupt

21.9
