BIT

BIT NAME

DEFAULT

DESCRIPTION

Receive Error Latch:

This bit will be cleared upon a read of the RECR register.

Receive Error Latch

0, RO/LH

1 = Receive error event has occurred since last read of RXERCNT

(address 0x15, Page 0)

0 = No receive error event has occurred

Polarity Status:

This bit is a duplication of bit 4 in the 10BTSCR register. This bit will

be cleared upon a read of the 10BTSCR register, but not upon a read

Polarity Status

0, RO

of the PHYSTS register.

1 = Inverted Polarity detected

0 = Correct Polarity detected

False Carrier Sense Latch:

This bit will be cleared upon a read of the FCSR register.

False Carrier Sense

0, RO/LH

1 = False Carrier event has occurred since last read of FCSCR

Latch

(address 0x14)

0 = No False Carrier event has occurred

Signal Detect

0, RO/LL

100Base-TX unconditional Signal Detect from PMD

Descrambler Lock

0, RO/LL

100Base-TX Descrambler Lock from PMD

Link Code Word Page Received:

This is a duplicate of the Page Received bit in the ANER register, but

this bit will not be cleared upon a read of the PHYSTS register.

Page Received

0, RO

1 = A new Link Code Word Page has been received. Cleared on read

of the ANER (address 0x06, bit 1)

0 = Link Code Word Page has not been received

MII Interrupt Pending:

1 = Indicates that an internal interrupt is pending. Interrupt source can

MII Interrupt

0, RO

be determined by reading the MISR Register (0x12h). Reading the

MISR will clear the Interrupt.

0= No interrupt pending

Remote Fault:

1 = Remote Fault condition detected (cleared on read of BMSR

Remote Fault

0, RO

(address 01h) register or by reset). Fault criteria: notification from Link

Partner of Remote Fault via Auto-Negotiation.

0 = No remote fault condition detected

Jabber Detect: This bit only has meaning in 10 Mb/s mode

This bit is a duplicate of the Jabber Detect bit in the BMSR register,

except that it is not cleared upon a read of the PHYSTS register.

Jabber Detect

0, RO

1 = Jabber condition detected

0 = No Jabber

Auto-Negotiation Complete:

Auto-Neg Complete

0, RO

1 = Auto-Negotiation complete

0 = Auto-Negotiation not complete

Loopback:

Loopback Status

0, RO

1 = Loopback enabled

0 = Normal operation
