  2. I²C - Wikipedia

    en.wikipedia.org/wiki/I²C

    Since OpenBSD 3.9 (released 1 May 2006; 18 years ago ()), a central i2c_scan subsystem probes all possible sensor chips at once during boot, using an ad hoc weighting scheme and a local caching function for reading register values from the I 2 C targets; [26] this makes it possible to probe sensors on general-purpose off-the-shelf i386/amd64 ...

  3. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    The key SPI parameters are: the maximum supported frequency for the serial interface, command-to-command latency, and the maximum length for SPI commands. It is possible to find SPI adapters on the market today that support up to 100 MHz serial interfaces, with virtually unlimited access length.

  4. Solicited-node multicast address - Wikipedia

    en.wikipedia.org/wiki/Solicited-node_multicast...

    A solicited-node multicast address is an IPv6 multicast address used by the Neighbor Discovery Protocol to determine the link layer address associated with a given IPv6 address, which is also used to check if an address is already being used by the local-link or not, through a process called DAD (Duplicate Address Detection). The solicited-node ...

  5. Serial presence detect - Wikipedia

    en.wikipedia.org/wiki/Serial_presence_detect

    In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

    Goals of the MIPI Sensor Working Group effort were first announced in November 2014 at the MEMS Executive Congress in Scottsdale AZ. [8]Electronic design automation tool vendors including Cadence, [9] Synopsys [10] and Silvaco [11] have released controller IP blocks and associated verification software for the implementation of the I3C bus in new integrated circuit designs.

  8. PIC microcontrollers - Wikipedia

    The ROM address space is 512 and may only specify addresses in the first half of each 512-word page. That is, the CALL instruction specifies the low 9 bits of the address, but only the low 8 bits of that address are a parameter of the instruction, while the 9th bit (bit 8) is implicitly specified as 0 by the CALL instruction itself.
