2 Preface
The objective of this data sheet is to define the func-
tionality of the Super Mapper for hardware and soft-
ware developers. The information contained in this data
sheet is preliminary, and may change without notice;
the reader must therefore ascertain that the latest ver-
sion is used when a product is under development.

2.2 Naming Convention for Registers and
There are many provisioning registers for controlling
the Super Mapper. A naming convention for all regis-
ters and parameters (bit names) is followed throughout
this data sheet. A prefix is attached to the base name
of each register or parameter, depending on which
functional section the register or parameter is associ-
ated with:
A suffix is appended to the base name of three com-
mon parameters:
SMPR_, for the Microprocessor Interface
TMUX_, for the TMUX
SPE_, for the SPE Mapper
VT_, for the VT/VC Mapper
M13_, for the M13/M23 MUX/deMUX
FRM_, for the 28-Channel Framer
XC_, for the Cross Connect
DJA_, for the Digital Jitter Attenuator
TPG_ and TPM_, for the Test-Pattern Generator/
Detection
_IS, for interrupt signal.
_IM, for interrupt mask.
_SWRS, for software reset.
