SetRegion(D4pccard)

SetRegion -- Describes region characteristics

Syntax (Used with unsupported services)

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

Description

The SetRegion structure allows a client to set a PC Card's region's characteristics. This allows region characterics to be set when they are not available in the CIS.

Structure definition

   unsigned short  	usSocket;
   unsigned short  	usAttributes;
   unsigned long   	ulCardOffset;
   unsigned long   	ulRegionSize;
   unsigned long   	ulEffBlockSize;
   unsigned short  	usPartMultiple;
   unsigned short  	usJedecID;
   unsigned long   	ulBaseOffset;
   unsigned char   	ucAccessSpeed;

Structure members

The members are defined as:

usSocket

Logical socket.

usAttributes

Valid values are:

bit 0

memory type (set = attribute)

bit 1

delete region (set = true)

bit 2

reserved (reset to zero)

bits 3-4

prefetchable/cacheable

0: neither
1: prefetchable only
2: both prefetchable and chacheable
3: reserved; do not use

bits 5-7

reserved (reset to zero)

bit 8

virtual region (set = true)

bits 9-12

reserved (reset to zero)

bits 13-15

base address register number (1-7)

ulCardOffset

Card memory region offset

ulRegionSize

Region size.

ulEffBlockSize

Erase block size.

usPartMultiple

Partition multiple.

usJedecID

Partition JEBEC memory I/O code.

ulBaseOffset

Address bias for MTD.

ucAccessSpeed

Window speed.
