All timing parameters are measured at the connector of the
device to which the parameter applies. For example, the

Note: The definitions for the IDE_IOW[0:1]# (STOP[0:1]), IDE_IOR[0:1]# (HDMARDY[0:1]#) and IDE_IRDY[0:1]
(DSTROBE[0:1]) signal lines are not in effect until IDE_REQ[0:1] and IDE_DACK[0:1]# are asserted.
