I'm looking at what the spec says. ;-) The read command delay from the head set command is 15us (so I was wrong) but still not a lot of time (that is after a head set, a read command must be at least 15us later). <snip> ----- And after the read command is given there is a gap, usually all zeros, at the end of which is a sync byte which is then followed by the first good data (or header) byte. In SMD the gaps can be 20 or 30 bytes long so there is quite a bit of time until good data. Tom
