PRODUCTION DATA.
| BIT | BIT NAME | DEFAULT | DESCRIPTION | ||||||
|---|---|---|---|---|---|---|---|---|---|
| 15 | MDIX_EN | Strap, RW | Auto-MDIX Enable: | ||||||
| 1 = Enable Auto-neg Auto-MDIX capability | |||||||||
| 0 = Disable Auto-neg Auto-MDIX capability | |||||||||
| The Auto-MDIX algorithm requires that the Auto-Negotiation Enable bit in the BMCR register to be set. If Auto-Negotiation is not enabled, Auto-MDIX should be disabled as well. | |||||||||
| 14 | FORCE_MDIX | 0, RW | Force MDIX: | ||||||
| 1 = Force MDI pairs to cross | |||||||||
| (Receive on TPTD pair, Transmit on TPRD pair) | |||||||||
| 0 = Normal operation | |||||||||
| 13 | PAUSE_RX | 0, RO | Pause Receive Negotiated: | ||||||
| Indicates that pause receive should be enabled in the MAC. Based on ANAR[11:10] and ANLPAR[11:10] settings. | |||||||||
| This function shall be enabled according to IEEE 802.3 Annex 28B Table 28B-3, “Pause Resolution”, only if the Auto-Negotiated Highest Common Denominator is a full duplex technology. | |||||||||
| 12 | PAUSE_TX | 0, RO | Pause Transmit Negotiated: | ||||||
| Indicates that pause transmit should be enabled in the MAC. Based on ANAR[11:10] and ANLPAR[11:10] settings. | |||||||||
| This function shall be enabled according to IEEE 802.3 Annex 28B Table 28B-3, “Pause Resolution”, only if the Auto-Negotiated Highest Common Denominator is a full duplex technology. | |||||||||
| 11 | BIST_FE | 0, RW/SC | BIST Force Error: | ||||||
| 1 = Force BIST Error | |||||||||
| 0 = Normal operation | |||||||||
| This bit forces a single error, and is self clearing | |||||||||
| 10 | PSR_15 | 0, RW | BIST Sequence select: | ||||||
| 1 = PSR15 selected | |||||||||
| 0 = PSR9 selected | |||||||||
| 9 | BIST_STATUS | 0, LL/RO | BIST Test Status: | ||||||
| 1 = BIST pass | |||||||||
| 0 = BIST fail. Latched, cleared when BIST is stopped | |||||||||
| For a count number of BIST errors, see the BIST Error Count in the CDCTRL1 register. | |||||||||
| 8 | BIST_START | 0, RW | BIST Start: | ||||||
| 1 = BIST start | |||||||||
| 0 = BIST stop | |||||||||
| 7 | BP_STRETCH | 0, RW | Bypass LED Stretching: | ||||||
| This will bypass the LED stretching and the LEDs will reflect the internal value. | |||||||||
| 1 = Bypass LED stretching | |||||||||
| 0 = Normal operation | |||||||||
| 6 | LED_CNFG[1] | 0, RW | LEDs Configuration: | ||||||
| 5 | LED_CNFG[0] | Strap, RW | LED_CNFG[1] | LED_ CNFG[0] | Mode Description | ||||
| Don’t care | 1 | Mode 1 | |||||||
| 0 | 0 | Mode 2 | |||||||
| 1 | 0 | Mode 3 | |||||||
| In Mode 1, LEDs are configured as follows: | |||||||||
| LED_LINK = ON for Good Link, OFF for No Link | |||||||||
| LED_SPEED = ON in 100 Mbps, OFF in 10 Mbps | |||||||||
| LED_ACT/COL = ON for Activity, OFF for No Activity | |||||||||
| In Mode 2, LEDs are configured as follows: | |||||||||
| LED_LINK = ON for good Link, BLINK for Activity | |||||||||
| LED_SPEED = ON in 100 Mbps, OFF in 10 Mbps | |||||||||
| LED_ACT/COL = ON for Collision, OFF for No Collision | |||||||||
| Full Duplex, OFF for Half Duplex | |||||||||
| In Mode 3, LEDs are configured as follows: | |||||||||
| LED_LINK = ON for Good Link, BLINK for Activity | |||||||||
| LED_SPEED = ON in 100 Mbps, OFF in 10 Mbps | |||||||||
| LED_ACT/COL = ON for Full Duplex, OFF for Half Duplex | |||||||||
| 4:0 | PHYADDR[4:0] | Strap, RW | PHY Address: PHY address for port | ||||||
