SJA1105 Tiamstamp

[BravoEven]

Hello :

   I am configing the timestamp function of the SJA1105Q and I want to know can the registers below be changed during runtime? As they are recommonded to be the source of ingress and engress timestamp it should be changed to fix the main time of the domain area, but I cannot find a way to change them, so I must use the PTPCLKVAL registers as the source of timestamp?

  Thanks!

Hi BravoEven,

That is correct, PTPCLKVAL needs to be used for runtime configurations. More details on this topic can be found in AH1704 under section 7.3.4 "Reconstruction for META frames".
