SocLib Components General Index
VciI2cInterface
1) Functional Description
This VCI target is an I2C controller. This hardware component saves in its FIFO all requests then handles them to be transmitted via I2C bus successively. The slave’s address is defined by a base address (I2C controller address on VCI bus) and a size (number of slaves). The I2C controller send an interruption to the processor to inform that data collected from I2C bus is ready. The segments allocated to a given instance of this component are defined in the Mapping Table.
