Table 10-12. PHY Status Register (PHYSTS), address 0x10 (continued)
Bit Bit Name Default Description
13 RECEIVE ERROR 0, RO/LH Receive Error Latch:
LATCH
This bit will be cleared upon a read of the RECR register.
1 = Receive error event has occurred since last read of RXERCNT (address
15h, Page 0).
0 = No receive error event has occurred.
12 POLARITY STATUS 0, RO 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 of the PHYSTS
register.
1 = Inverted Polarity detected.
0 = Correct Polarity detected.
11 FALSE CARRIER SENSE 0, RO/LH False Carrier Sense Latch:
LATCH
This bit will be cleared upon a read of the FCSR register.
1 = False Carrier event has occurred since last read of FCSCR (address 14h).
0 = No False Carrier event has occurred.
10 SIGNAL DETECT 0, RO/LL 100Base-TX qualified Signal Detect from PMA:
This is the SD that goes into the link monitor. It is the AND of raw SD and
descrambler lock, when address 16h, bit 8 (page 0) is set. When bit 8 of
address 16h is cleared, it will be equivalent to the raw SD from the PMD.
9 DESCRAMBLER LOCK 0, RO/LL 100Base-TX Descrambler Lock from PMD.
8 PAGE RECEIVED 0, RO 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.
1 = A new Link Code Word Page has been received. Cleared on read of the
ANER (address 06h, bit 1).
0 = Link Code Word Page has not been received.
7 MII INTERRUPT 0, RO MII Interrupt Pending:
1 = Indicates that an internal interrupt is pending. Interrupt source can be
determined by reading the MISR Register (12h). Reading the MISR will clear
the Interrupt.
0 = No interrupt pending.
6 REMOTE FAULT 0, RO Remote Fault:
1 = Remote Fault condition detected (cleared on read of BMSR (address 01h)
register or by reset). Fault criteria: notification from Link Partner of Remote
Fault via Auto-Negotiation.
0 = No remote fault condition detected.
5 JABBER DETECT 0, RO 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.
1 = Jabber condition detected.
0 = No Jabber.
4 AUTO-NEG COMPLETE 0, RO Auto-Negotiation Complete:
1 = Auto-Negotiation complete.
0 = Auto-Negotiation not complete.
3 LOOPBACK STATUS 0, RO Loopback:
1 = Loopback enabled.
0 = Normal operation.
