One question for host guys:
What will you do if you assert ATN and then the phase which the drive
enters to receive the messages is CMD? Don't you do a phase check to
make sure that your are in the right phase?
If you do the phase check, a broken ATN is not worth worrying about
since you will see CMD phase and 6, 10 or 12 bytes requested by the
target. Many of the chips I have seen have an interrupt for a phase
mismatch. Isn't this whole arguement a mute point?
Regards,
Jeff
