The in-circuit emulator that allows you to test the project in a hardware environment, while
viewing the debugging device activity in a software environment (PSoC Designer).
A suspension of a process, such as the execution of a computer program, caused by an event
external to that process, and performed in such a way that the process can be resumed.
A block of code that normal code execution is diverted to when the M8C receives a hardware
interrupt. Many interrupt sources may each exist with its own priority and individual ISR code
block. Each ISR code block ends with the RETI instruction, returning the device to the point in
the program where it left normal program execution.
A circuit that senses V
An 8-bit Harvard-architecture microprocessor. The microprocessor coordinates all activity inside
a PSoC by interfacing to the Flash, SRAM, and register space.
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 I/O circuitry. The reason
for this is to permit the realization of a controller with a minimal quantity of chips, thus
achieving maximal possible miniaturization. This in turn, reduces 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.
A device that imposes a signal on a carrier.
A circuit that may be crystal controlled and is used to generate a clock frequency.
A technique for testing transmitting data. Typically, a binary digit is added to the data to make the
sum of all the digits of the binary data either always even (even parity) or always odd (odd parity).
An electronic circuit that controls an oscillator so that it maintains a constant phase angle relative
to a reference signal.
The pin number assignment: the relation between the logical inputs and outputs of the PSoC
device and their physical counterparts in the printed circuit board (PCB) package. Pinouts
involve pin numbers as a link between schematic and PCB design (both being computer generated
files) and may also involve pin names.
