Table 245 Trusted Receive Command (5Ch)
The Trusted Receive command reads one or more 512 byte packets from the drive. The returned packets depend on
the Security Protocol selected (feature). See Trusted Command Feature for details.
The sectors are transferred through the Data Register 16 bits at a time.
