RequestConfiguration -- describes the socket and PC Card to be configured

Syntax

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

Description

The RequestConfiguration structure is used to configure the PC Card and socket. This service must be used by clients that require DMA channel routing, I/O windows to be enabled, and IRQ number routing.

Structure definition

   unsigned short  	usSocket;
   unsigned short  	usAttributes;
   unsigned char   	ucVcc;
   unsigned char   	ucVpp1;
   unsigned char   	ucVpp2;
   unsigned char   	ucIntType;
   unsigned long   	ulConfigBase;
   uchar ucStatus
   uchar			ucPin
   uchar			ucCopy
   uchar			ucConfigIndex
   uchar			ucPresent
   uchar			ucExtendedStatus

Structure members

The members are defined as:

usSocket

Low bite indicates socket. High bite indicates function.

usAttributes

Valid values are:

bit 0: reserved (reset to 0)
bit 1: set (1) = enable IRQ steering
bit 25: eserved (reset to 0)
bit 6: set (1) = enable DMA channel
bit 78: reserved (reset to 0)
bit 9: VSOVERRIDE set (1); override VS pins disabling voltage protection
bit 1015: eserved (reset to 0)

ucVcc

Vcc setting.

ucVpp1

Vpp1 setting.

ucVpp2

Vpp2 setting.

ucIntType

Memory or memory plus I/O.

bit 0: memory, set (1) = true
bit 1: memory and I/O, set (1) = true
bit 2: IF_CARDBUS, set (1) = true
bit 37: reserved (reset to 0)

Note that bits 0, 1, and 2 are mutually exclusive. Only one of these may be set.

ulConfigBase

Base address of configuration registers.

bit 0: option
bit 1: status
bit 2: pin replacement
bit 3: copy
bit 4: extended status
bit 57: reserved (reset to 0)

ucStatus

Card status register setting.

ucPin

Card pin register setting.

ucCopy

Card socket/copy register setting.

ulConfigIndex

Card option register setting.

ucPresent

Card configuration registers that are present.

ucExtendedStatus

Extended status register setting.
