  2. PIC instruction listings - Wikipedia

    For example, MOVW copies the value of W to the destination. When used with d = 1, this stores W to f. There is a matching MOVF instruction which outputs the value of f. When used with d = 0, this loads f into W. When used with d = 1, the only visible effect is to set the zero flag depending on the value of f.

  3. Universal asynchronous receiver-transmitter - Wikipedia

    Example of a UART frame. In this diagram, one byte is sent, consisting of a start bit, followed by eight data bits (D1-8), and two stop bits, for a 11-bit UART frame. The number of data and formatting bits, the presence or absence of a parity bit, the form of parity (even or odd) and the transmission speed must be pre-agreed by the ...

    en.wikipedia.org/wiki/Block_diagram

    An example of this is the function block diagram, one of five programming languages defined in part 3 of the IEC 61131 (see IEC 61131-3) standard that is highly formalized (see formal system), with strict rules for how diagrams are to be built. Directed lines are used to connect input variables to block inputs, and block outputs to output ...

    en.wikipedia.org/wiki/Interrupt_request

    Diagram about the course of an interrupt routine In a computer , an interrupt request (or IRQ ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler , to run instead.

    Alternatively, diagram source is passed through the preprocessor to produce a file for insertion into the document source. A version of pic is included in groff , the GNU version of troff. GNU pic can also act as a preprocessor for TeX documents, emitting its own tpic DVI specials , which aren't as widely supported as those of other TeX graphic ...

  7. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

    Typical SoC use in a system on a module circuit board SoM block diagram example. A system on a module (SoM) is a board-level circuit that integrates a system function in a single module. It may integrate digital and analog functions on a single board. A typical application is in the area of embedded systems.

    An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
