13.25 Smart Card Configuration 1 Register
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 1 alias register in the Smart Card global control register
set. The software utilizes this information and adjusts the software and firmware behavior if necessary.
Corresponding bits are tied to 0 if the socket is not implemented.
Class A and B support are depend on the system and integrated device. Supporting both classes requires method
(pins) to control 5.0 V and 3.0 V.
Default value and bit types are depending on the device. When this core is integrated into a device and does not have
all four sockets, removed sockets bits must be tied to 0 and changed to read-only bits.
See Table 13−15 for a complete description of the register contents. All bits in this register are reset by GRST only.
