glossary/symbols, terms, and definitions
A
absolute addressing mode:
An addressing mode in which code or operands produce the actual address
address:
Any given memory location in which data can be stored or from which data can be retrieved
addressing mode:
The method by which an instruction calculates the location of its required data
analog-to-digital converter (ADC):
circuitry. Also referred to as ADC1, ADC2, or ADC3. ADC1 is an 8-channel ADC, except for the 40-pin
TMS370Cx4x devices which have only four channels. ADC2 is a 4-channel ADC. And ADC3 is a 15-channel ADC.
An 8-bit successive-approximation converter with internal sample-and-hold
ANSI C:
tional Standards Institute
A version of the C programming language that conforms to the C standards defined by the American Na-
archiver:
library. The archiver also allows the addition, deletion, extraction, or replacement of members of the archive library.
A software program that allows the collection of several individual files into a single file called an archive
assembler:
language instructions, directives, and macro directives. The assembler substitutes absolute operation codes for
symbolic operation codes, and absolute or relocatable addresses for symbolic addresses.
A software program that creates a machine-language program from a source file containing assembly
assembly language:
of the 73 unique instructions of the TMS370 family converts to one machine operation.
A symbolic language that describes the binary machine code in a more readable form. Each
asynchronous-communications mode:
communications mode format consists of a start bit followed by data bits, an optional parity bit, and a stop bit. This
format commonly is used with RS-232-C communications and PC serial ports.
An SCI mode that needs no synchronizing clock. The asynchronous
B
baud:
The communication speed for serial ports; equivalent to bits per second
BCD:
Binary coded decimal.Each 4-bit nibble expresses a digit from 0–9 and usually packs two digits to a byte,
giving a range of 0–99.
bit:
Contraction of binary digit i.e., a 1 or a 0. In electrical terms, the value of a bit can be represented by the pres-
ence or absence of charge, voltage, or current.
breakpoint, trace, and timing (BTT) features:
XDS/22 emulation system). These features allow the setting of hardware breakpoints, collecting of trace samples,
and performing timing analysis.
A set of features supported by the BTT board (included with the
buffer pointer:
the circular-capture buffer
A 5-bit register in the PACT module peripheral frame that points to the next available location in
byte:
A sequence of eight adjacent bits operated upon as a unit
