I come up against same problem on this forum in my design, that is
"when design ATA host , i met with the problem:after hardware reset, power on or software reset, the host designed by me , has red the value from the registers such as status register, LBA low register , LBA High register LBA mid register, or Device register in ATA hard disk(MAXTOR 250G). To my surprise, the values are the same: 0xFF7F."
I want to know how solve the problem, if you know it, please tell me. thanks.
