2. Now look for a device at Bus=01,Device=01, Function=00. It is a Bridge so we look up the Bus
number. Lets say its 2
3. Now look for a device at Bus=02,Device=03, Function=00. It is a Bridge so we look up the Bus
number. Lets say its 4
4. Now look for a device at Bus=04,Device=03, Function=00. It is a Bridge so we look up the Bus
number. Lets say its 5
5. So the Next Port number == 0xFF so we know we now have our Express Card Port. Namely
• Express Card Port Bridge is Bus=04, Device=03 Function=00.
• Device Address is Bus 5.
6.3 Serial Port Configuration Block
typedef struct SerPortCfgBlock_s{
DBlockIdHdr_t DBHdr ; /* 0x00 Dynamic Block Header */
uint8_t SerIRQ ; /* 0x03 */
uint8_t Ser0BaseAddr[2] ; /* 0x04 Serial Port 0 */
uint8_t Ser1BaseAddr[2] ; /* 0x06 Serial Port 1 */
}SerPortCfgBlock_t;
CAP_C_STRUCT 3: Express Card Extended Topology
6.3.1 Description
The configuration EEPROM may use One block to indicate the prefered configuration of up to 2 Serial
Ports. If no block is present the bios defaults are used.
6.3.2 Block Elements
6.3.2.1 DBHdr
See ' 6.1 Common Dynamic Block Header' on page 31.
