10.7.10 Command Register

- CS0

DA2-DA0 : 7

Write only

The command register accepts commands for the drive to perform fixed disk operations. Commands are executed when the TASK FILE is loaded and the command register is written and only when:

The status is not busy (BSY is inactive). and

DRDY (drive ready) is active.

Any code NOT defined in the following list causes an Aborted Command error. Interrupt request (INTRQ) is reset when a command is written. The following are acceptable commands to the command register.
