In AmigaOS one can use the i2c.resource component [25] for AmigaOS 4.x and MorphOS 3.x or the shared library i2c.library by Wilhelm Noeker for older systems. Arduino developers can use the "Wire" library. CircuitPython and MicroPython developers can use the busio.I2C or machine.I2C classes respectively.
Part II of the PMBus specification covers every standard PMBus command. It also describes the models for managing output power and current, managing faults, converting values to and from the formats understood by a given device, and accessing manufacturer-provided information such as inventory data (model and serial number, etc.) and device ...
Inter-Integrated Circuit Sound (I²S, pronounced "eye-squared-ess" [citation needed]) is a serial interface protocol for transmitting two-channel, digital audio as pulse-code modulation (PCM) between integrated circuit (IC) components of an electronic device. An I²S bus separates clock and serial data signals, resulting in simpler receivers ...
I2C and I3C are also an example of master-slave technology. Modbus uses a master device to initiate connection requests to slave devices. An edge-triggered flip-flop can be created by arranging two gated latches in a master–slave configuration. It is so named because the master latch controls the slave latch's value and forces the slave latch ...
But reset, simple addressed reads and writes, movement of blocks of data, and indivisible bus cycles all work without tags. Wishbone is open source . To prevent preemption of its technologies by aggressive patenting, the Wishbone specification includes examples of prior art , to prove its concepts are in the public domain.
I3C targets which do not support HDR may then ignore bus traffic until they see a specific "HDR exit" sequence which informs them it is time to listen to the bus again. (One of the I2C Common Command Codes lets the controller ask a target which HDR modes it supports. This is an 8-bit mask, allowing additional HDR modes to be added in future.)
In modern protocol design, protocols are layered to form a protocol stack. Layering is a design principle that divides the protocol design task into smaller steps, each of which accomplishes a specific part, interacting with the other parts of the protocol only in a small number of well-defined ways.
In a performance-oriented design or a design with only one eSPI sub, each eSPI sub will have its Alert# pin connected to an Alert# pin on the eSPI main that is dedicated to each sub, allowing the eSPI main to grant low-latency service, because the eSPI main will know which eSPI sub needs service and will not need to poll all of the subs to ...
