7.6.1 Basic Mode Control Register (BMCR)

Table 7-10 Basic Mode Control Register (BMCR), Address 0x0000
BITBIT NAMEDEFAULTDESCRIPTION
15RESET0, RW/SCReset:
1 = Initiate software Reset / Reset in Process.
0 = Normal operation.
This bit, which is self-clearing, returns a value of one until the reset process is complete. The configuration is restrapped.
14LOOPBACK0, RWLoopback:
1 = Loopback enabled.
0 = Normal operation.
The loopback function enables MAC transmit data to be routed to the MAC receive data path.
Setting this bit may cause the descrambler to lose synchronization and produce a 500µs dead time before any valid data will appear at the MII receive outputs.
13SPEED SELECTION LSB0, RWSpeed Select (Bits 6, 13):
When auto-negotiation is disabled writing to this bit allows the port speed to be selected.
11 = Reserved
10 = 1000Mbps
1 = 100Mbps
0 = 10Mbps
12AUTO-NEGOTIATION ENABLEStrap, RWAuto-Negotiation Enable:
Strap controls initial value at reset.
1 = Auto-Negotiation Enabled - bits 8 and 13 of this register are ignored when this bit is set.
0 = Auto-Negotiation Disabled - bits 8 and 13 determine the port speed and duplex mode.
11POWER DOWN0, RWPower Down:
1 = Power down.
0 = Normal operation.
Setting this bit powers down the PHY. Only the register block is enabled during a power down condition. This bit is ORd with the input from the PWRDOWN_INT pin. When the active low PWRDOWN_INT pin is asserted, this bit will be set.
10ISOLATE0, RWIsolate:
1 = Isolates the Port from the MII with the exception of the serial management.
0 = Normal operation.
9RESTART AUTO-NEGOTIATION0, RW/SCRestart Auto-Negotiation:
1 = Restart Auto-Negotiation. Reinitiates the Auto-Negotiation process. If Auto-Negotiation is disabled (bit 12 = 0), this bit is ignored. This bit is self-clearing and will return a value of 1 until Auto-Negotiation is initiated, whereupon it will self-clear. Operation of the Auto-Negotiation process is not affected by the management entity clearing this bit.
0 = Normal operation.
8DUPLEX MODEStrap, RWDuplex Mode:
When auto-negotiation is disabled writing to this bit allows the port Duplex capability to be selected.
1 = Full Duplex operation.
0 = Half Duplex operation.
7COLLISION TEST0, RWCollision Test:
1 = Collision test enabled.
0 = Normal operation.
When set, this bit will cause the COL signal to be asserted in response to the assertion of TX_EN within 512-bit times. The COL signal will be deasserted within 4-bit times in response to the deassertion of TX_EN.
6SPEED SELECTION MSB1, RWSpeed Select: See description for bit 13.
5:0RESERVED0 0000, RORESERVED: Write ignored, read as 0.
