An 8-bit Harvard Architecture microprocessor. The microprocessor coordinates all activity inside
a PSoC by interfacing to the Flash, SRAM, and register space.
A programming language macro is an abstraction whereby a certain textual pattern is replaced
according to a defined set of rules. The interpreter or compiler automatically replaces the macro
instance with the macro contents when an instance of the macro is encountered. Therefore, if a
macro is used 5 times and the macro definition required 10 bytes of code space, 50 bytes of
code space will be needed in total.

2. A pattern of bits that can be used to retain or suppress segments of another pattern of bits in
A device that controls the timing for data exchanges between two devices. Or when devices are
cascaded in width, the master device is the one that controls the timing for data exchanges
between the cascaded devices and an external interface. The controlled device is called the
slave device .
An integrated circuit chip that is designed primarily for control systems and products. In addition
to a CPU, a microcontroller typically includes memory, timing circuits, and IO circuitry. The rea-
son for this is to permit the realization of a controller with a minimal quantity of chips, thus
achieving maximal possible miniaturization. This, in turn, will reduce the volume and the cost of
the controller. The microcontroller is normally not used for general-purpose computation as is a
microprocessor.
The reference to a circuit containing both analog and digital techniques and components.
1. A tool intended to assist the memory. Mnemonics rely on not only repetition to remember
2. A two to four character string representing a microprocessor instruction.
A distinct method of operation for software or hardware. For example, the Digital PSoC block
may be in either counter mode or timer mode.
A range of techniques for encoding information on a carrier signal, typically a sine-wave signal. A
device that performs modulation is known as a modulator.
A device that imposes a signal on a carrier.
An acronym for metal-oxide semiconductor.
The binary digit, or bit, in a binary number that represents the most significant value (typically the
left-hand bit). The bit versus byte distinction is made by using a lower case “b” for bit in MSb.
The byte in a multi-byte word that represents the most significant value (typically the left-hand
byte). The byte versus bit distinction is made by using an upper case “B” for byte in MSB.
