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. 86h/EAh - ITT VPX 32xx - Diverse Settings Bitfields for VPX 32xx diverse settings: Bit(s) Description (Table I0039) 2-0 reserved (0) 3 connect LLC2 to ALPHA/TDO pin 4 LLC/2 polarity 5 output FIFO pointer reset select 0 on positive edge of VACTref 1 on VRF=0 7-6 officially reserved 6 =1 wraps to top before bottom of image (3220A) 7 =1 freeze image (3220A)
