12.1 Direct Commands

Table 12-1 Direct Commands Table

Command	Name	Units	Type	Access	Description
0x00	Control Status	Hex	H2	Sealed: R/W Unsealed: R/W Full Access: R/W	When read, this command provides device status bits. This command behaves similarly to 0x3E/0x3F when written. When read back immediately after word write, it will return 0xFFA5 once. Subsequent reads will return Control Status. Writing this command is used for legacy auto-detection, and it is not recommended for customers to write to it. Bit descriptions can be found in Section 13.2.1.
