Preliminary
3.1.12. CARDBUS CIS Pointer
This register indicates the head address for the EPROM (BIOS ROM) that contains the card bus information.
When the device is released from a hardware reset, it automatically loads the required data from the externally
connected EEPROM.

3.1.13. Subsystem
This register indicates the subsystem and subsystem- vendor ID (product ID) to identify the MB86613S device
when it is connected together with another device on the same add- on board. The data are automatically
loaded from the external EEPROM when the chip is released from the hardware reset.
