Port 1 Control Register (0xF6 – 0xF7): P1CR
This register contains the global per port control for the chip function.
Bit
Default
R/W
Description
Bit is same as:
15
0
RW
LED Off
1 = Turn off all of the port 1 LEDs (P1LED3, P1LED2,
P1LED1, P1LED0). These pins are driven high if this bit is
set to one.
0 = normal operation.
Bit 0 in P1MBCR
14
0
RW
Txids
1 = disable the port’s transmitter.
0 = normal operation.
Bit 1 in P1MBCR
13
0
RW
Restart AN
1 = restart auto-negotiation.
0 = normal operation.
Bit 9 in P1MBCR
12
0
RW
Reserved
11
0
RW
Reserved
10
0
RW
Disable auto MDI/MDI-X
1 = disable auto MDI/MDI-X function.
0 = enable auto MDI/MDI-X function.
Bit 3 in P1MBCR
9
0
RW
Force MDI-X
1= if auto MDI/MDI-X is disabled, force PHY into MDI-X
mode.
0 = do not force PHY into MDI-X mode.
Bit 4 in P1MBCR
8
0
RW
Reserved
7
1
RW
Auto Negotiation Enable
1 = auto negotiation is enabled.
0 = disable auto negotiation, speed, and duplex are decided
by bits 6 and 5 of the same register.
Bit 12 in P1MBCR
6
1
RW
Force Speed
1 = force 100BT if AN is disabled (bit 7).
0 = force 10BT if AN is disabled (bit 7).
Bit 13 in P1MBCR
5
1
RW
Force Duplex
1 = force full duplex if (1) AN is disabled or (2) AN is
enabled but failed.
0 = force half duplex if (1) AN is disabled or (2) AN is
enabled but failed.
Bit 8 in P1MBCR
4
1
RW
Advertised flow control capability.
1 = advertise flow control (pause) capability.
0 = suppress flow control (pause) capability from
transmission to link partner.
Bit 10 in P1ANAR
3
1
RW
Advertised 100BT full-duplex capability.
1 = advertise 100BT full-duplex capability.
0 = suppress 100BT full-duplex capability from transmission
to link partner.
Bit 8 in P1ANAR
2
1
RW
Advertised 100BT half-duplex capability.
1 = advertise 100BT half-duplex capability.
0 = suppress 100BT half-duplex capability from transmission
to link partner.
Bit 7 in P1ANAR
1
RW
Advertised 10BT full-duplex capability.
