PPS signal on LS1021A TSN

[muaslam]

Hi,
Currently, I am using LS1021A TSN for clock synchronization. I wonder if the switch has exposed PPS port to measure clock synchronization? If yes, may I learn how to configure it?
I could not find much information about it in user manual.

LS1021A-TSN does not have provisions for PPS output. SJA1105T cannot generate
them, on LS1021A these signals are multilexed and their corresponding pins are
used for other purposes. If your application requires both L2 TSN switch and PPS
outputs, consider using the next generation TSN board, LS1028A-RDB
