Glossary
burst-mode a high-speed data transfer in which the address of the data is sent followed
by back-to-back data words while a physical signal is asserted
bus the group of conductors that interconnect individual circuitry in a computer.
Typically, a bus is the expansion vehicle to which I/O or other devices are
connected. Examples of PC buses are the AT bus, NuBus, Micro Channel,
and EISA bus.
bus master a type of a plug-in board or controller with the ability to read and write
devices on the computer bus
C
C Celsius
channel pin or wire lead to which you apply or from which you read the analog or
digital signal. Analog signals can be single-ended or differential. For digital
signals, you group channels to form ports. Ports usually consist of either
four or eight digital channels.
channel clock the clock controlling the time interval between individual channel sampling
within a scan. Boards with simultaneous sampling do not have this clock.
chromatograph an instrument used in chemical analysis of gases and liquids.
CI computing index
circuit trigger a condition for starting or stopping clocks
CIRQ0 PPI C interrupt request bit for Port A
CIRQ1 PPI C interrupt request bit for Port B
clock hardware component that controls timing for reading from or writing to
groups
CMOS complementary metal-oxide semiconductor
coupling the manner in which a signal is connected from one location to another
CPA bidirectional lines for Port A of PPI C
CPB bidirectional lines for Port A of PPI C
