The registers of the SC26C198 are partitioned into two groups:
those used in controlling data channels and those used in handling
the actual data flow and status. Below is shown the general
configuration of all the register addressed. The ”Register Map
Summary” shows the configuration of the lower four bits of the
address that is the same for the individual UARTs. It also shows the
addresses for the several in the address space of UART A and

Map Detail” shows the use of every address in the 8 bit address
space.
NOTE: The register maps for channels A and B (UARTs A and B)
contain some control registers that configure the entire chip. These
are denoted by a
symbol.
