Addressing example:
The address for the LCR register of UART channel 5 is:
PCI Base Address
(PCI Base Address for the Device Configuration Space)
+ 0x0A00
(Offset of the UART register set for serial channel 5)
+ 0x0003
(Offset of the LCR register within a UART register set)
For a detailed description of the serial channel registers please refer to the XR17D158 data sheet
which is available on the Exar website (
