Command Register
The host sends a command to the drive by means of an 8-bit code written to the
Command Register. As soon as the drive receives the command in its Command
Register, it begins execution of the command. Table 6-17 lists the hexadecimal
command codes and parameters for each executable command. The code F0h is
common to all of the extended commands. Each of these commands is distinguished
by a unique subcode. For a detailed description of each command, see Section 6.7,
"COMMAND DESCRIPTIONS," found later in this chapter.
