EPOCHs
There are three Owner EPOCH modes (Each EPOCH is 64bit): no
change in owner epoch, change to new random owner epoch and
manually entered by user. After generating new epoch via 'Change
to New Random Owner EPOCHs', the selection reverts back to 'No
Change in Owner Epochs', this is to ensure Epoch stays same,
across Sx states. After the user enters epoch values manually, the
values will not be visible, for security reasons.
