10.12 Reset

A RESET condition sets the drive ( or both drives in case of Master/Slave connection ) BSY, allowing the
drive to perform the specified initialization required for normal operation.

A RESET condition can be generated by both hardware and software. There are two hardware resets, one
is by the Host (- RESET) and the other is by the drive power sense circuitry. These resets are set high
when the system and the drive respectively acknowledge specified supply voltage ( See 6.1).

The other reset is software generated. The Host can write to the Device Control register and set the

reset bit. The host software condition will continue until the reset bit is set to zero.

.

        Once the reset is negated and the drive is re-enabled, with BSY still active, the drive will perform
        necessary hardware initialization, clear any previously programmed drive parameters and revert
        to the defaults, load the Task File registers with their initial values, and then clear BSY. No interrupt
        is generated when initialization is complete. The initial values ( hex ) for the Task File registers are
        as follows.

ATA-2 Notes: This register is obsolete. It is recommended that a device not respond to a read of this address. If a

device does respond, it shall be sure not to drive the DD7 signal to prevent possible conflict with floppy disk
implementations.
The drive supports this register to maintain compatibility for ATA-1.

13

ATA-2 Notes: The default mode for write cache is “disable” after ATA-2. This is violation of ATA-2 specification. This setting can be

changed by factory.
