ModifyConfiguration(D4pccard)

ModifyConfiguration -- describe modification of a socket and PC Card configuration

Syntax

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

Description

The ModifyConfiguration structure is used to allow a socket and PC Card configuration to be modified.

Structure definition

   unsigned short  	usSocket;
   unsigned short  	usAttributes;
   unsigned char   	ucReserved;
   unsigned char   	ucVpp1;
   unsigned char   	ucVpp2;

Structure members

The members are defined as:

usSocket

Card function. usSocket is two bytes long. The more significant byte indicates the function. The function of single function cards is mapped to zero. The functions of multi-function cards are enumerated from zero on up to the number of functions available less one. The low byte in usSocket indicates logical socket.

usAttributes

Bit-mapped member.

bit 0: reserved (reset to 0)
bit 1: enable IRQ steering, set (1) = true
bit 2: IRQ change valid (set = true).
bit 3: ignored
bit 4: Vpp1 change valid, set (1) = true
bit 5: Vpp2 change valid, set (1) = true
bit 6: enable DMA channel, set (1) = true
bit 7: DMA change valid, true
bit 8: reserved (reset to 0)
bit 9: VSOVERRIDE, set (1) = override VS pins (overrides card voltage protection)
bit 10-15: reserved (reset to 0)

ucReserved

Reserved.

ucVpp1

Vpp1 setting.

ucVpp2

Vpp2 setting.

Usage

This service can only modify a configuration that is requested with the RequestConfiguration(D3pccard) service.

Hardware applicability

All
