I2C
Having two I2C modules on the TMS320C6713/13B simplifies system architecture, since one module may be
used by the DSP to control local peripherals ICs (DACs, ADCs, etc.) while the other may be used to
communicate with other controllers in a system or to implement a user interface.
The TMS320C6713/13B also includes two I2C serial ports for control purposes. Each I2C port supports:
Compatible with
Philips I
2
C Specification Revision 2.1
(January 2000)
Fast Mode up to 400 Kbps (no fail-safe I/O buffers)
Noise Filter to Remove Noise 50 ns or less
Seven- and Ten-Bit Device Addressing Modes
Master (Transmit/Receive) and Slave (Transmit/Receive) Functionality
Events: DMA, Interrupt, or Polling
Slew-Rate Limited Open-Drain Output Buffers
