This bit enables the IPv4 MAC address of 01:00:5E:00:01:83 and IPv4 desti-

nation address of 224.0.1.131 for PTP packets.

This bit enables the IPv6 MAC address of 33:33:00:00:01:83 and IPv6 desti-

nation address of FF0X:0:0:0:0:0:0:183 for PTP packets.

Note:

The host S/W must not change this bit while the 1588 Enable

(1588_ENABLE) bit in 1588 Command and Control Register

(1588_CMD_CTL) is set.

R/W

This bit enables the IPv4 MAC address of 01:00:5E:00:01:84 and IPv4 desti-

nation address of 224.0.1.132 for PTP packets.

This bit enables the IPv6 MAC address of 33:33:00:00:01:84 and IPv6 desti-

nation address of FF0X:0:0:0:0:0:0:184 for PTP packets.

Note:

The host S/W must not change this bit while the 1588 Enable

(1588_ENABLE) bit in 1588 Command and Control Register

(1588_CMD_CTL) is set.

R/W

RX Address 5 Enable (RX_ADD5_EN)

This bit enables the IPv4 MAC address of 01:00:5e:00:00:6B and IPv4 desti-

nation address of 224.0.0.107 for PTP packets.

This bit enables the IPv6 MAC address of 33:33:00:00:00:6B and IPv6 desti-

nation address of FF02:0:0:0:0:0:0:6B for PTP packets.

Note:

The host S/W must not change this bit while the 1588 Enable

(1588_ENABLE) bit in 1588 Command and Control Register

(1588_CMD_CTL) is set.

R/W

RX User Defined Layer 2 MAC Address Enable

(RX_LAYER2_USER_MAC_EN)

This bit enables a user defined Layer 2 MAC address in PTP messages.

Note:

The host S/W must not change this bit while the 1588 Enable

(1588_ENABLE) bit in 1588 Command and Control Register

(1588_CMD_CTL) is set.

R/W

RX User Defined IPv6 MAC Address Enable (RX_IPV6_USER_MAC_EN)

This bit enables a user defined IPv6 MAC address in PTP messages.

Note:

The host S/W must not change this bit while the 1588 Enable

(1588_ENABLE) bit in 1588 Command and Control Register

(1588_CMD_CTL) is set.

R/W

RX User Defined IPv4 MAC Address Enable (RX_IPV4_USER_MAC_EN)

This bit enables the user defined IPv4 MAC address in PTP messages. The

address is defined via the 1588 User MAC Address High-WORD Register

(1588_USER_MAC_HI) and the 1588 User MAC Address Low-DWORD

Note:

The host S/W must not change this bit while the 1588 Enable
