A unique identifier of the PSoC device.
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
See positive edge .
An acronym for read only memory. A data-storage device from which data can be read out, but
new data cannot be written in.
A block of code, called by another block of code, that may have some general or frequent use.
Physically connecting objects in a design according to design rules set in the reference library.
In digital circuits, narrow pulses that, due to non-zero rise and fall times of the signal, do not
reach a valid high or low level. For example, a runt pulse may occur when switching between
asynchronous clocks or as the result of a race condition in which a signal takes two separate
paths through a circuit. These race conditions may have different delays and are then recom-
bined to form a glitch or when the output of a flip-flop becomes metastable.
The process of converting an analog signal into a series of digital values or reversed.
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.
An initial value loaded into a linear feedback shift register or random number generator.
1. Pertaining to a process in which all events occur one after the other.
2. Pertaining to the sequential or consecutive occurrence of two or more related activities in a
To force a bit/register to a value of logic 1.
The time it takes for an output signal or value to stabilize after the input has changed from one
value to another.
The movement of each bit in a word, one position to either the left or right. For example, if the
hex value 0x24 is shifted one place to the left, it becomes 0x48. If the hex value 0x24 is shifted
one place to the right, it becomes 0x12.
A memory storage device that sequentially shifts a word either left or right to output a stream of
serial data.
The most significant binary digit, or bit, of a signed binary number. If set to a logic 1, this bit rep-
resents a negative quantity.
A detectable transmitted energy that can be used to carry information. As applied to electronics,
any transmitted electrical impulse.
A unique identifier of the PSoC silicon.
