4.2 Configuration EEPROM
After power-on or PCI reset, the XR17D154 loads initial configuration register data from the on board
configuration EEPROM.
The configuration EEPROM contains the following configuration data:
•
Vendor ID
•
Vendor Device ID
•
SubSystem Vendor ID
•
SubSystem Device ID
See the XR17D154 Manual for more information.

Subsystem-ID Value (Offset 0x0C): TPMC467-10R 0x000A
TPMC467-11R 0x000B
The words following the configuration data contain:
•
The module version and revision
•
The UART clock frequency in Hz
•
The physical interface attached to the serial channels
•
The maximal baud rate of the transceivers in bps
•
The supported control signals of the serial channels
For the physical interfaces and the control signals applies: Bit 3 represents UART channel 3 and bit 0
represents UART channel 0. The appropriate bit is set to ‘1’ for each UART channel attached to the
physical interface represented by the word. Bit 15 to bit 4 are always ‘0’.
