Select Owner EPOCH input type
Option Default: 00
00 = No Change in Owner EPOCHs
01 = Change to New Random Owner EPOCHs
02 = Manual User Defined Owner EPOCHs
Option Help: 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.
