18.1 Features
Preliminary User’s Manual U17566EE1V2UM00
The V850E/Dx3 microcontrollers have following instances of the I
interface IIC:
Throughout this chapter, the individual instances of
identified by “n”, for example IICn, or IICCn for the IICn control register.
The I²C provides a synchronous serial interface with the following features:
• Supports Master and Slave mode
• 8-bit data transfer
• Transfer speed
• I
• Two wire interface
• Noise filter on SCLn and SDAn input
• IICn interrupts can be used for triggering the DMA Controller
