SCRTCH_PAD
RW
Scratch pad
2725
RSVD
R
Reserved. These bits return 000b when read.
24
CLASS_B_SKT0
RW
Socket 0 Class B Smart Card support. When this bit is set to 1b, socket 0 supports Class B Smart
Cards.
2321
RSVD
R
Reserved. These bits return 000b when read.
20
CLASS_A_SKT0
RW
Socket 0 Class A Smart Card support. When this bit is set to 1b, socket 0 supports Class A Smart
Cards.
1917
RSVD
R
Reserved. These bits return 000b when read.
16
EMVIF_EN_SKT0
RW
Socket 0 EMV interface enable. When this bit is set to 1b, the internal EVM interface for socket
0 is enabled.
1513
RSVD
R
Reserved. These bits return 000b when read.
12
GPIO_EN_SKT0
RW
Socket 0 GPIO enable. When this bit is set to 1b, the SC_GPIOs for socket 0 are enabled.
119
RSVD
R
Reserved. These bits return 000b when read.
8
PCMCIA_MODE_SKT0
R/W
Socket 0 PCMCIA mode. If the SC_SOCKET_SEL bit is 0, this bit must be programmed to 0.
If the SC_SOCKET_SEL bit is 1, this bit must be programmed to 1.
75
RSVD
R
Reserved. These bits return 000b when read.
4
PME_SUPPORT_SKT0
RW
Socket 0 PME support. When this bit is set to 1b, socket 0 card insertions cause a PME event.
31
RSVD
R
Reserved. These bits return 000b when read.
0
SKT0_EN
RW
Socket 0 enable. When this bit is set to 1b, socket 0 is enabled.
13.26 Smart Card Configuration 2 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 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 1316 for a complete description of the register contents. All bits in this register are reset by GRST
only.
Function 4 register offset: 54h
Register type:
Read-only, Read/Write (EEPROM, GRST only)
Default value:
0000 0000h

3116
RSVD
R
Reserved. Bits 3116 return 0000h when read.
158
PWRUP_DELAY_
PCMCIA
R
Power up delay for the PCMCIA socket. This register indicates how long the external power
switch takes to apply stable power to the PCMCIA socket in ms. Software must wait before
starting operation after power up. This field has no effect for the hardware.
70
RSVD
R
Reserved. Bits 70 return 00h when read.
