REGISTER MAPS
The registers of the SC28L194 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
UART B that apply to the total chip configuration. The “Register 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
