HOST SOFTWARE INTERFACE

CommandRegister

Contains code for the command to be performed. Additional command information should be written to the task file before the Command register is loaded. When this register is written, the BUSY bit in the Status register sets, and interrupt request to the host clears; invalid commands abort. (Detailed information on interface commands is given in Section 7.) Hex values for valid command formats follow:
