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.
Any programming using the SC28L202 as it is intended would
always use the address space form 0x10 through 0x7F. For the
REGISTER MAP DETAIL (based on 28L92)
NOTE: Addresses 0x00 to 0x0F represent the ‘C92 Register’ map.

most part, differences in address between channel A and B differ by
0x08.
The first address from 0x00 to 0x0F refer to the legacy code for
previous Philips/Signetics two channel UARTs (DUARTs). This
feature is directed to the SC26C92. That part has 89-byte FIFOs,
but powers up to look like it has a 3-byte receiver FIFO and a 1-byte
transmitter FIFO. Other control registers structures of legacy parts
are compatible back to the SCN2681.
Registers that configure the whole chip are denoted by a ‘ ’
symbol.
