- Send TPer Reset command to reset eDrive to lock all protected bands.\r
- Typically, there are 2 mechanism for resetting eDrive. They are:\r
- 1. TPer Reset through IEEE 1667 protocol.\r
- 2. TPer Reset through native TCG protocol.\r
- This routine will detect what protocol the attached eDrive comform to, TCG or\r
- IEEE 1667 protocol. Then send out TPer Reset command separately.\r
