CARD_CONFIG_INFO

The CARD_CONFIG_INFO structure contains PC Card configuration information. This structure is passed to CardRequestConfiguration. All members are input only.

Syntax

typedef struct {
CARD_SOCKET_HANDLE hSocket;
UINT16 fAttributes;
UINT8 fInterfaceType;
UINT8 uVcc; UINT8 uVpp1;
UINT8 uVpp2;
UINT8 fRegisters;
UINT8 uConfigReg;
UINT8 uStatusReg;
UINT8 uPinReg;
UINT8 uCopyReg;
UINT8 uExtendedStatus;
} CARD_CONFIG_INFO, *PCARD_CONFIG_INFO;

Members

hSocket

Specifies a handle to a socket and function pair.

fAttributes

Contains a bitmask for specifying IRQ, DMA, and voltage options.

CFG_ATTR_IRQ_STEERING

Enables the IRQ steering in socket controller.

CFG_ATTR_ENABLE_DMA

Enables DMA.

fInterfaceType

Contains a bitmask specifying memory or I/O interface

CFG_IFACE_MEMORY

Puts socket controller in memory only interface mode.

CFG_IFACE_MEMORY_IO

Put socket controller in memory and I/O interface mode.

uVcc

Specifies the Vcc voltage to use in 0.1 volt increments.

uVpp1

Specifies the Vpp1 voltage to use in 0.1 volt increments.

uVpp2

Specifies the Vpp2 voltage to use in 0.1 volt increments.

fRegisters

Specifies a bitmask indicating which registers are present. Each of these bits indicates the presence one of the standard function and configuration registers in the attribute space of the PC Card. By calling CardRequestConfiguration, a driver can set these registers to desired initial values.

CFG_REGISTER_CONFIG

Indicates the configuration option register (uConfigReg) contains data.

CFG_REGISTER_STATUS

Indicates the function configuration and status register (uStatusReg) contains data.

CFG_REGISTER_PIN

Indicates the pin replacement register (uPinReg) contains data.

CFG_REGISTER_COPY

Indicates the socket and copy register (uCopyReg) contains data.

CFG_REGISTER_EXSTATUS

Indicates the extended status register (uExtendedStatus) contains data.

uConfigReg

Specifies the initial bitmask value to write to a configuration option register.

The lower six bits of the configuration option register specify which configuration number to use for single function cards.

FCR_COR_LEVEL_IREQ

1 = level mode interrupts, 0 = pulse mode.

FCR_COR_SRESET

1 = soft reset.

uStatusReg

Specifies the initial value to write to a function status register. The following bitmask values are defined:

FCR_FCSR_INTR_ACK

Acknowledge interrupt.

FCR_FCSR_INTR

Interrupt pending.

FCR_FCSR_PWR_DOWN

Place PC Card in power down mode.

FCR_FCSR_AUDIO

Enable audio signal on BUD2 (pin 62).

FCR_FCSR_IO_IS_8

Used by host to indicated 8-bit-only I/O.

FCR_FCSR_STSCHG

Enable status change (STSCHG, pin 63) from PC Card.

FCR_FCSR_CHANGED

Specify whether one of the status changed bits is set in the pin replacement register.

uPinReg

Specifies the initial value to write to a pin replacement register.

uCopyReg

Specifies the initial value to write to a socket and copy register.

uExtendedStatus

Specifies the initial value to write to an extended status register.

Remarks

Card Services remembers the base address of the configuration registers, so there is no need for a uConfigBase member.
