Global wear-leveling algorithm eliminate excessive write operation and extends product life. · Suppot StaticDataRefresh & EarlyRetirement technology to monitor error bit level and react before data is corrupted. thin-clients or industrial PCs. [. . . ] It is used by the device to request a reset from the host in accordance to the sequence shown in Figure 6, below. Figure 6 : cominit sequence Description: 1. Host/device are powered and operating normally with some form of active communication. Device responds ­ The device detects the COMWAKE sequence on its RX pair and calibrates its transmitter (optional). Following calibration the device sends a six burst COMWAKE sequence and then sends a continuous stream of the ALIGN sequence starting at the device's highest supported speed. After ALIGNP Dwords have been sent for 54. 6 us (2048 nominal Gen1 Dword times) without a response from the host as determined by detection of ALIGNP primitives received from the host, the device assumes that the host cannot communicate at that speed. If additional speeds are available the device tries the next lower supported speed by sending ALIGNP Dwords at that rate for 54. 6 us (2048 nominal Gen1 Transcend Information Inc. 11 V0. 5 TS2G~16GCFX500 reached without response from the host, the device enters an error state. CFast Card Dword times. ) This step is repeated for as many slower speeds as are supported. Host locks ­ after detecting the COMWAKE, the host starts transmitting D10. 2 characters at its lowest supported rate. Meanwhile, the host receiver locks to the ALIGN sequence and, when ready, returns the ALIGN sequence to the device at the same speed as received. A host shall be designed such that it acquires lock in 54. 6 us (2048 nominal Gen1 Dword times) at any given speed. The host should allow for at least 873. 8 us (32768 nominal Gen1 Dword times) after detecting the release of COMWAKE to receive the first ALIGNP. This ensures interoperability with multi-generational and synchronous designs. If no ALIGNP is received within 873. 8 us (32768 nominal Gen1 Dword times) the host restarts the power-on sequence ­ repeating indefinitely until told to stop by the Application layer. Device locks ­ the device locks to the ALIGN sequence and, when ready, sends SYNCP indicating it is ready to start normal operation.

Device locks ­ the device locks to the ALIGN sequence and, when ready, sends the SYNCP primitive indicating it is ready to start normal operation. Upon receipt of three back-to-back non-ALIGNP primitives, the communication link is established and normal operation may begin.

[. . . ] The transferred data contains a user or master password, which the drive compares with the saved password. If they match, the drive deletes user data, disables the user password, and cancels the lock. It is re-enabled by issuing the SECURITY SET PASSWORD command to re-set a user password. SECURITY FREEZE LOCK (F5h) Causes the drive to enter Frozen mode. Once this command has been executed, the following commands to update a lock result in the Aborted Command error: · SECURITY SET PASSWORD · SECURITY UNLOCK · SECURITY DISABLE PASSWORD · SECURITY ERASE PREPARE · SECURITY ERASE UNIT Transcend Information Inc. 21 V0. 5 TS2G~16GCFX500 CFast Card The drive exits from Frozen mode upon a power-off or hard reset.
