DESCRIPTION

15−8

BIST

R

Built-in self-test. The Smart Card controller does not include a BIST; therefore, this field returns 00h
when read.

7−0

HEADER_TYPE

R

PCI header type. The Smart Card controller includes the standard PCI header. Bit 7 indicates if the Smart
Card is a multifunction device.

13.8 Smart Card Base Address Register 0

This register is used by this function to determine where to forward a memory transaction to the Smart Card global
control register set. Bits 31−12 of this register are read/write and allow the base address to be located anywhere in
the 32-bit PCI memory space on 4-Kbyte boundary. The window size is always 4K bytes. Bits 11−0 are read-only and
always return 0s. Write transactions to these bits have no effect. Bit 3 (0b) specifies that this window is
nonprefetchable. Bits 2−1 (00b) specify that this memory window can allocate anywhere in the 32-bit address space.
