A hardware and software system that allows the user to analyze the operation of the system
under development. A debugger usually allows the developer to step through the firmware one
step at a time, set break points, and analyze memory.
A period of time when neither of two or more signals are in their active state or in transition.
A base-10 numbering system, which uses the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 (called digits)
together with the decimal point and the sign symbols + (plus) and - (minus) to represent num-
bers.
Pertaining to the pre-defined initial, original, or specific setting, condition, value, or action a sys-
tem will assume, use, or take in the absence of instructions from the user.
The device referred to in this manual is the PSoC chip, unless otherwise specified.
An unpackaged integrated circuit (IC), normally cut from a wafer.
A signal or function, the amplitude of which is characterized by one of two discrete values: ‘0’ or
‘1’.
The 8-bit logic blocks that can act as a counter, timer, serial receiver, serial transmitter, CRC
generator, pseudo-random number generator, or SPI.
A methodology for dealing with expressions containing two-state variables that describe the
behavior of a circuit or system.
A device that changes a digital signal to an analog signal of corresponding magnitude. The ana-
log-to-digital (ADC) converter performs the reverse operation.
The capability to obtain data from a storage device, or to enter data into a storage device, in a
sequence independent of their relative positions by means of addresses that indicate the physi-
cal location of the data.
The relationship of a clock period high time to its low time , expressed as a percent.
Duplicates (provides an emulation of) the functions of one system with a different system, so that
the second system appears to behave like the first system.
An active high signal that is driven into the PSoC device. It causes all operation of the CPU and
blocks to stop and return to a pre-defined state.
A transition from a logic 1 to a logic 0. Also known as a negative edge.
The return of a portion of the output, or processed portion of the output, of a (usually active)
device to the input.
A device or process by which certain frequency components of a signal are attenuated.
