tUI is an unlimited interlock, that has no maximum time value. tMLI is a limited time-out that has a defined minimum. tLI is a limited time-out, that has a defined maximum. 2) All timing parameters are measured at the connector of the device to which the parameter applies. For example, the sender shall stop generating STROBE edges tRFS after the negation of DMARDY-. Both STROBE and DMARDY- timing measurements are taken at the connector of the sender. 3) All timing measurement switching points (l

(17) READ LONG (X’22’ or X’23’) This command operates similarly to the READ SECTOR(S) command except that the device transfers the data in the requested sector and the ECC bytes to the host system. The ECC error correction is not performed for this command. This C141-E050-02EN 5-43 Interface command is used for checking ECC function by combi

4-20 C141-E050-02EN 4.7 Servo Control d) During phase switching, the spindle motor starts rotating in low speed, and generates a counter electromotive force. The SVC detects this counter electromotive force and reports to the MPU using a PHASE signal for speed detection. e) The MPU is waiting for a PHASE signal. When no phase signal is sent for a sepcific period, the MPU resets the SVC and starts from the beginning. When a PHASE signal is sent, the SVC enters the acceleration mode. (2) Accelerat
