11.2 Register initialization After a power on, a hard reset, or a software reset, the register values are initialized as shown in the table below. Table 45: Default Register Values Register Error Sector Count LBA Low LBA Mid LBA High Device Status Alternate Status Default Value Diagnostic Code 01h 01h 00h 00h A0h 50h 50h If an Execute Device Diagnostic command is carried out, if the system is powered on, or if a hard reset occurs, the system generates an Error Register diagnostic code. See the table below for a description of the codes.
