Alternate MAC Address 1 Enable Port 0(External MII)
(MAC_ALT1_EN_MII)
This bit enables/disables the alternate MAC address 1 on Port 0.
0: Disables alternate MAC address on Port 0
1: Enables MAC address 01:00:5E:00:01:82 as a PTP address on Port 0
Alternate MAC Address 2 Enable Port 0(External MII)
(MAC_ALT2_EN_MII)
This bit enables/disables the alternate MAC address 2 on Port 0.
0: Disables alternate MAC address on Port 0
1: Enables MAC address 01:00:5E:00:01:83 as a PTP address on Port 0
Alternate MAC Address 3 Enable Port 0(External MII)
(MAC_ALT3_EN_MII)
This bit enables/disables the alternate MAC address 3 on Port 0.
0: Disables alternate MAC address on Port 0
1: Enables MAC address 01:00:5E:00:01:84 as a PTP address on Port 0
User Defined MAC Address Enable Port 0(External MII)
(MAC_USER_EN_MII)
This bit enables/disables the auxiliary MAC address on Port 0. The auxiliary
address is defined via the 1588_AUX_MAC_HI and 1588_AUX_MAC_LO
registers.
0: Disables auxiliary MAC address on Port 0
1: Enables auxiliary MAC address as a PTP address on Port 0
Lock Enable RX Port 0(External MII) (LOCK_RX_MII)
This bit enables/disables the RX lock. This lock prevents a 1588 capture
from overwriting the Clock, UUDI and Sequence ID values if the 1588 RX
interrupt for Port 0 is ready set due to a previous capture.
0: Disables RX Port 0 Lock
1: Enables RX Port 0 Lock
Note:
Lock Enable TX Port 0(External MII) (LOCK_TX_MII)
This bit enables/disables the TX lock. This lock prevents a 1588 capture
from overwriting the Clock, UUDI and Sequence ID values if the 1588 TX
interrupt for Port 0 is ready set due to a previous capture.
0: Disables TX Port 0 Lock
1: Enables TX Port 0 Lock
Note:
RESERVED
Lock Enable GPIO 9 (LOCK_GPIO_9)
This bit enables/disables the GPIO 9 lock. This lock prevents a 1588 capture
from overwriting the Clock value if the 1588_GPIO9 interrupt in the
Interrupt Status and Enable Register (1588_INT_STS_EN)
due to a previous capture.
0: Disables GPIO 9 Lock
1: Enables GPIO 9 Lock
For Port 0, receive is defined as data from the switch fabric, while
transmit is to the switch fabric.
For Port 0, receive is defined as data from the switch fabric, while
transmit is to the switch fabric.
