RBIL61 - HTML Edition

Welcome to the HTML Edition (r314) of the famous "Ralf Brown's Interrupt List". Although the most recent release of the Interrupt List is now more than 20 years old, the fundamentals of DOS development haven't changed that much. Ralf's List remains one of the foremost resources for low level DOS programming. You can still download the original Interrupt List release files directly from the files section of Ralf's website (http://www.cs.cmu.edu/~ralf/).

I2C(also IIC; the "2" is superscripted) Inter-Integrated Circuit Bus -- A moderate-speed serial communications bus originally invented by Philips in the early 1980s for consumer-electronics applications, such as inter-chip communication in a television set or high-end stereo. The I2C bus has recently appeared on PCs in video capture boards and similar devices, as well as (surprisingly) SDRAM DIMMs (for the on-board serial EEPROM). The ACCESS.bus is a derivative of the I2C bus which forms the physical layer of the Universal Serial Bus. Similary, the SMBus (System Management Bus) also uses I2C as its physical layer. Bus Devices
