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.
