Techniques for performing finger merge protection (FMP) using polling. Whenever a command to adjust the timing of a designated finger is received, other fingers "on the same channel" (i.e., those for which merge protection is sought) are polled for permission to apply the command. The designated finger sets a poll request and provides other pertinent information to an FMP storage unit. Thereafter, each of the other fingers on the same channel determines whether or not applying the command would result in that finger merging with the designated finger. Merging may be detected if the difference between the timing (or offsets) of the two fingers is less than a specified offset spacing. Any finger on the same channel may disallow the command if merging is detected. The designated finger would then adjust its timing if the command is not disallowed by any of the fingers on the same channel. |
