6.1.1Response to power-on

After the master device (device 0) releases its own power-on reset state, the master device shall check a DASP- signal for up to 450 ms to confirm presence of a slave device (device 1). The master device recognizes presence of the slave device when it confirms assertion of the DASP- signal. Then, the master device checks a PDIAG- signal to see if the slave device has successfully completed the power-on diagnostics.

If the master device cannot confirm assertion of the DASP- signal within 450 ms, the master device recognizes that no slave device is connected.

After the slave device (device 1) releases its own power-on reset state, the slave device shall report its presence and the result of power-on diagnostics to the master device as described below:

DASP- signal: Asserted within 400 ms, and negated after the first command is received from the host or within 31 seconds or after executing software reset, which ever comes first.

PDIAG- signal: Negated within 1 ms and asserted within 30 seconds, then negated within 31 seconds.

When the unrecoverable error occurs during the write operation, the command execution is stopped. Then, when the drive receives the next command, it generates an interrupt of abnormal end. However an interrupt of abnormal end is not generated when a write automatic assignment succeeds. However, since the host may issue several write commands before the drive generates an interrupt of abnormal end, the host cannot recognize that the occurred error is for which command generally. Therefore, it is very hard to retry the unrecoverable write error for the host in the write cache operation generally. So, take care to use the write cache function I, Place des Etas-Unis, SILIC 310, 94588 Rungis Cedex, FRANCE Reader Comment Form FUJITSU LIMITED
