IEEE 1588v2 and LS1021A

[jamessun]

Regarding the IEEE 1588v2 support by LS1021A, it is supported for all THREE Ethernet Controllers simultaneously?

Hello James Sun,

LS1021 processor provides hardware assist for IEEE 1588 protocal. IEEE 1588 compliant time stamping on the device is accomplished using the per-port transmit time stamping registers with each Ethernet controller memory space, all TSEC  can use this assistance in the same way and use hardware time-tamp mechanism simultaneously.

Please note common 1588 time stamping registers exist within the eTSEC1 memory space, the eTSEC1 controller must remain enabled in order to use 1588 time stamping for any Ethernet port.

Have a great day,
Yiping
