For ROM (Read Only) and OTP (One Time Programmable) types of the SD Memory Card, the security feature is optional. In the case of Standard Capacity SD Memory Card, this field shall be set to 2 (Version 1.01). In the case of High Capacity SD Memory Card, this field shall be set to 3 (Version 2.00).

SD_BUS_WIDTHS

Describes all the DAT bus widths that are supported by this card.

Since SD Memory Card shall support at least the two bus modes 1bit or 4bit width then any SD Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101").
