GLOSSARY
C
SAR
Successive approximation register.
SASM
Single action submodule.
SCI
Serial communications interface.
Set
‘1’ — the logic one state; the opposite of ‘clear’.
Silicon Glen
An area in the central belt of Scotland, so called because of the concentration of
semiconductor manufacturers and users found there.
SIM
System integration module; a module on an IMB device that reduces the need for
external glue logic by providing an external interface and a variety of other system
related functions.
Single chip mode
In this mode the device functions as a self contained unit, requiring only I/O devices
to complete a system.
Slave
The module that responds to a master's request.
SMB
Submodule bus; the internal CTM bus that allows exchange of information between
submodules.
SPI
Serial peripheral interface.
State
Subunit of the bus cycle in which specific events occur. Each state has a duration of
one clock tic, and represents a single state within the controlling microengine. For the
IMB, the states defined include B1, B2, B2*, B3, B4 and B4*.
Submodule
A functional block that defines a CTM function. Most of the submodules can be placed
several times in order to obtain the desired system.
Test mode
This mode is intended for factory testing.
Tic
A clock tic is defined as the single high or low state, irrespective of that state being
represented by a high or low voltage level. For a 16.67MHz, a clock tic has a duration
of 30ns.
Transaction
The transfer of data between two modules (a master and a slave) using the IMB and
its established protocol. A single transaction may require multiple bus cycles.
TTL
Transistor-transistor logic.
UART
Universal asynchronous receiver transmitter.
VCO
Voltage controlled oscillator.
Watchdog
See‘COP’.
Wired-OR
A means of connecting outputs together such that the resulting composite output
state is the logical OR of the state of the individual outputs.
Word
Two bytes; 16 bits.
XIRQ
Non-maskable interrupt request. The overline indicates that this has an active-low
signal format.
F
.
