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.

Value	Description
CFG_ATTR_IRQ_STEERING	Enables IRQ steering in the socket controller.
CFG_ATTR_ENABLE_DMA	Enables DMA.
CFG_ATTR_IRQ_WAKEUP	Allow PCMCIA interrupts to wake the system.
CFG_ATTR_KEEP_POWERED	Keep the PCMCIA bus powered during suspend.

fInterfaceType

Contains a bitmask specifying memory or I/O interface.

Value	Description
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 requires.

Value	Description
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.

Value	Description
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:

Value	Description
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 uConfigBasemember.
