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 Layer 2 Address 2 Enable (RX_LAYER2_ADD2_EN)

This bit enables the Layer 2 MAC address of 01:1B:19:00:00:00 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
