Bits
Description
4
RX IP Address Enable (RX_IP_ADDR_EN)
This bit enables the checking of the IP destination address in PTP messages
for both IPv4 and IPv6 formats.
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.
3
RX MAC Address Enable (RX_MAC_ADDR_EN)
This bit enables the checking of the MAC destination address in PTP mes-
sages.
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.
2
RX Layer 2 Enable (RX_LAYER2_EN)
This bit enables the detection of the layer 2 formatted 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.
1
RX IPv6 Enable (RX_IPV6_EN)
This bit enables the detection of the UDP/IPv6 formatted 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.
0
RX IPv4 Enable (RX_IPV4_EN)
This bit enables the detection of the UDP/IPv4 formatted 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.
