ConfigurationInfo(D4pccard)

ConfigurationInfo -- information about the specified socket and PC Card configuration

Syntax

   #include <sys/lcs.h>
   #include <sys/lss.h>

Description

The ConfigurationInfo structure returns information about the configuration of the specified socket and the function of the PC Card in the socket.

Structure definition

The ConfigurationInfo structure contains the following members:

   unsigned long   	ulConfigBase;
   unsigned char   	ucStatus;
   unsigned char   	ucPin;
   unsigned char   	ucCopy;
   unsigned char   	ucOption;
   unsigned char   	ucPresent;
   unsigned char   	ucFirstDevType;
   unsigned char   	ucFuncCode;
   unsigned char   	ucSysInitMask;
   unsigned short  	usManufCode;
   unsigned short  	usManufInfo;
   unsigned char   	ucCardValues;
   unsigned char   	ucAssignedIRQ;
   unsigned short  	usIRQAttributes;
   unsigned short  	usBasePort1;
   unsigned char   	ucNumPort1;
   unsigned short  	usAttributes1;
   unsigned short  	usBasePort2;
   unsigned char   	ucNumPort2;
   unsigned short  	usAttributes2;
   unsigned char   	ucIOAddrLines;
   unsigned char   	ucExtendedStatus;
   unsigned short  	usDMAAttributes;
   unsigned char   	ucAssignedChannel;
   unsigned char   	ucNumIOWnds;
   unsigned char   	ucNumMemWnds;

Structure members

The members are defined as:

usSocket

Logical socket

usAttributes

Bit 0 always 1; bit 1 set to 1 for CardBus, set for 16-bit card; bit 8 set to 1 for valid client.

ucVcc

Vcc setting

Vpp1

Vpp1 setting

Vpp2

Vpp2 setting

ucIntType

Memory or memory plus I/O.

u1ConfigBase

Base address of configuration registers on card.

ucStatus

Card status register setting.

ucPin

Card pin register setting.

ucCopy

Card socket copy register setting.

ucOption

Card option register setting

ucPresent

Card configuration registers that are present.

ucFirstDevType

Read from card device ID tuple.

ucFuncCode

Read from card function ID tuple.

ucSysInitMask

Read from card function ID tuple.

usManufCode

Read from card manufacturer ID tuple.

usManufInfo

Read from card manufacturer ID tuple.

ucCardValues

Valid card register values.

usAssignedIRQ

Card's IRQ assigned by CardServices.

usIRQAttributes

IRQ attributes. Valid values are:

usBasePort1: base port address for range
usNumPort1: number of contiguous ports
usAttributes1: bit-mapped.

usBasePort2

Range base port address.

ucNumPort2

Count of contiguous ports.

usAttributes2

See usAttributes above.

ucIOAddrLines

16-bit card I/O address line count.

ucExtendedStatus

Setting for extended status register.

usDMAAttributes

Bit mapped.

bit 1 bit 0 Share Mode 0 0 DMA not shared 0 1 time-multiplexed sharing 1 0 dynamically shared 1 1 reserved

bit 3 bit 2 DMA request signal 0 0 reserved 0 1 DREQ# uses IOIS16# 1 0 DREQ# uses IOIS16# 1 1 DREQ# uses INPACK# bit 4 DMA data width 0 8 bits 1 16 bits

Bits 5, 6, and 7 are not used.

ucAssignedChannel

BCD 0-15; top 4 bits insignificant.

ucNumIOWnds

Count of I/O windows for logical socket

ucNumMemWnds

Count of memory windows.
