Chapter 17 Clocked Serial Interface (CSIB)
17.1 Features
Preliminary User’s Manual U17566EE1V2UM00
The V850E/Dx3 microcontrollers have following instances of the clocked serial
interface CSIB:
Throughout this chapter, the individual instances of clocked serial interface are
identified by “n”, for example CSIBn, or CBnCTL0 for the control register 0 of
CSIBn.
• Transfer rate: 8 Mbps to 2 kbps (using dedicated baud rate generator)
• Master mode and slave mode selectable
• 8-bit to 16-bit transfer, 3-wire serial interface
• 3 interrupt request signals (INTCBnT, INTCBnR, INTCBnRE)
• Serial clock and data phase switchable
• Transfer data length selectable in 1-bit units between 8 and 16 bits
• Transfer data MSB-first/LSB-first switchable
• 3-wire transfer
• DMA support
• Dedicated baud rate generator for each interface instance
• Modulated and stable clock sources available
