UART
The OPB memory map location of the OPB 16450 UART is determined by setting the parameter C_BASEADDR, in the IPIF
interface module. The internal registers of the OPB 16450 UART are offset from the C_BASEADDR base address. Addition-
ally, some of the internal registers are accessible only when bit 7of the Line Control Register (LCR) is set. The UART internal
register set is described in
