Datasheet

All data transfers to the device through the Data Register are 16 bits with the exception of the ECC bytes,

which are 8 bits.

13.3 Non-Data Commands

These commands are as follows:

y Check Power Mode

y Enable/Disable Delayed Write

y Execute Device Diagnostic

y Flush Cache

y Format Unit

y Idle

y Idle Immediate

y Initialize Device Parameters

y Read Native Max ADDRESS

y Read Verify Sectors

y Recalibrate

y Seek

y Sense condition

y Set Features

y Set Max ADDRESS

y Set Multiple Mode

y Standby

y Standby Immediate

Execution of these commands involves no data transfer.

The following are the steps in the execution process:

1. The host writes any required parameters to the Features, Sector Count, Sector Number, Cylinder,

and Device/Head Registers.

2. The host writes the command code to the Command Register.

3. The device sets BSY=1.

4. When the device has finished processing the command, it sets BSY=0, and interrupts the host.

5. In response to the interrupt, the host reads the Status Register.

6. The device clears the interrupt in response to the Status Register being read.
