(continued)
The objective of this data sheet is to define the func-
tionality of the Supermapper for hardware and software
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
Parameters
There are many provisioning registers for controlling
the Supermapper. A naming convention for all registers
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 func-
tional section the register or parameter is associated
with:
I
SMPR_, for the Microprocessor Interface
I
TMUX_, for the TMUX
I
SPE_, for the SPE Mapper
I
VT_, for the VT/VC Mapper
I
M13_, for the M13/M23 MUX/deMUX
I
FRM_, for the 28-Channel Framer
I
XC_, for the Cross Connect
I
DJA_, for the Digital Jitter Attenuator
I
TPG_ and TPM_, for the Test-Pattern Generator/
Detection
A suffix is appended to the base name of three com-
mon parameters:
I
_IS, for interrupt signal.
I
_IM, for interrupt mask.
I
_SWRS, for software reset.
