  2. Smart card application protocol data unit - Wikipedia

    en.wikipedia.org/wiki/Smart_card_application...

    There are two categories of APDUs: command APDUs and response APDUs. A command APDU is sent by the reader to the card – it contains a mandatory 4-byte header (CLA, INS, P1, P2) [2] and from 0 to 65 535 bytes of data. A response APDU is sent by the card to the reader – it contains from 0 to 65 536 bytes of data, and 2 mandatory status bytes ...

    8-bit command will be executed or last 4 bits of previous command; set 8-bit mode. In all three starting cases, the bus interface is now in 8-bit mode, 1 line, 5×8 characters. If a different configuration 8-bit mode is desired, an 8-bit bus Function Set command should be sent to set the full parameters.

    The Short Message protocol itself is defined by 3GPP TS 23.040 for the Short Message Service - Point to Point (SMS-PP), [2] and 3GPP TS 23.041 for the Cell Broadcast Service (CBS). [3] Four MAP procedures are defined for the control of the Short Message Service: [1] Mobile Originated (MO) short message service transfer;

    Push the size, in bytes, of a type as an unsigned int32. Object model instruction 0xFE 0x0B starg <uint16 (num)> Store value to the argument numbered num. Base instruction 0x10 starg.s <uint8 (num)> Store value to the argument numbered num, short form. Base instruction 0xA4 stelem <typeTok> Replace array element at index with the value on the ...

  7. CANopen - Wikipedia

    en.wikipedia.org/wiki/CANopen

    The basic datatypes for object dictionary values such as booleans, integers and floats are defined in the standard (their size in bits is optionally stored in the related type definition, index range 0x0001–0x001F), as well as composite datatypes such as strings, arrays and records (defined in index range 0x0040–0x025F). The composite ...

    Using a data size of 16 bits will cause only the bottom 16 bits of the 32-bit general-purpose registers to be modified – the top 16 bits are left unchanged.) The default OperandSize and AddressSize to use for each instruction is given by the D bit of the segment descriptor of the current code segment - D=0 makes both 16-bit, D=1 makes both 32 ...

  9. dd (Unix) - Wikipedia

    en.wikipedia.org/wiki/Dd_(Unix)

    dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
