REGISTER MAPS
The registers of the SC28L202 are LOOSELY 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.
