Abstract
A Serial Advanced Technology Attachment (SATA) device for communicating with a host is disclosed. The SATA device comprises control circuitry which enters a XRDY state in preparation for sending data to the host, receives a first XRDY from the host while in the XRDY state, and sets a RXRDY flag. After receiving the first XRDY, the control circuitry receives a RRDY from the host while in the XRDY state, transmits a data block to the host in response to the RRDY, and enters an idle state after transmitting the data block to the host. If the RXRDY flag is set while in the idle state, the control circuitry waits for the host to transmit a second XRDY.
