BIOS or EEPROM configure system dependent Smart Card interface information through this register. Information
of this register can be read from the Smart Card configuration 2 alias in the Smart Card global control register set.
The software utilizes this information and adjusts the software and firmware behavior, if necessary.
See Table 13−16 for a complete description of the register contents. All bits in this register are reset by GRST only.
