CARD_CONFIG_INFO

This structure contains PC Card configuration information. It is passed to the CardRequestConfiguration function. 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

Handle to a socket and function pair.

fAttributes

Contains a bitmask for specifying interrupt request (IRQ), Direct Memory Access (DMA), and voltage options.

CFG_ATTR_IRQ_STEERING

Enables IRQ steering in the 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

Puts the socket controller in memory mode 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 of 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 whatever initial values the PC Card needs.

CFG_REGISTER_CONFIG

Indicates that the configuration option register (uConfigReg) contains data.

CFG_REGISTER_STATUS

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

CFG_REGISTER_PIN

Indicates that the pin replacement register (uPinReg) contains data.

CFG_REGISTER_COPY

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

CFG_REGISTER_EXSTATUS

Indicates that the extended status register (uExtendedStatus) contains data.

uConfigReg

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

The lower 6 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 off mode.

FCR_FCSR_AUDIO

Enable audio signal on BVD2 (pin 62).

FCR_FCSR_IO_IS_8

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

FCR_FCSR_STSCHG

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

FCR_FCSR_CHANGED

Specifies 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.
