Power-on-Reset (POR)
A circuit that forces the enCoRe V device to reset when the voltage is below a pre-set level. This
is one type of
program counter
The instruction pointer (also called the program counter) is a register in a computer processor
that indicates where in memory the CPU is executing instructions. Depending on the details of
the particular machine, it holds either the address of the instruction being executed or the
address of the next instruction to be executed.
protocol
A set of rules. Particularly the rules that govern networked communications.
PSoC Designer™
The software for Cypress’ Programmable System-on-Chip technology.
pulse
A rapid change in some characteristic of a signal (for example, phase or frequency) from a base-
line value to a higher or lower value, followed by a rapid return to the baseline value.
R
RAM
An acronym for random access memory. A data-storage device from which data can be read out
and new data can be written in.
register
A storage device with a specific capacity, such as a bit or byte.
reset
A means of bringing a system back to a known state. See
and
.
resistance
The resistance to the flow of electric current measured in ohms for a conductor.
revision ID
A unique identifier of the enCoRe V device.
ripple divider
An asynchronous ripple counter constructed of flip-flops. The clock is fed to the first stage of the
counter. An n-bit binary counter consisting of n flip-flops that can count in binary from 0 to 2
n
- 1.
rising edge

ROM
An acronym for read-only memory. A data-storage device from which data can be read out, but
new data cannot be written in.
routine
A block of code, called by another block of code, that may have some general or frequent use.
routing
Physically connecting objects in a design according to design rules set in the reference library.
S
sampling
The process of converting an analog signal into a series of digital values or reversed.
schematic
A diagram, drawing, or sketch that details the elements of a system, such as the elements of an
electrical circuit or the elements of a logic diagram for a computer.
seed value
An initial value loaded into a linear feedback shift register or random number generator.
