Execution includes the transfer of one or more 512 byte (>512 bytes on Write Long) sectors of data from

the host to the device.

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. For each sector (or block) of data to be transferred:

a. The device sets BSY=0 and DRQ=1 when it is ready to receive a sector (or block).

b. The host writes one sector (or block) of data via the Data Register.

c. The device sets BSY=1 after it has received the sector (or block).

d. When the device has finished processing the sector (or block), it sets BSY=0 and interrupts the

host.

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

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

5. For the Write Long command:

a. The device sets BSY=0 and DRQ=1 when it is ready to receive a sector.

b. The host writes one sector of data including ECC bytes via the Data Register.

c. The device sets BSY=1 after it has received the sector.

d. After processing the sector of data the device sets BSY=0 and interrupts the host.

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