137 / 159 page  TMS570LS3137 www.ti.com SPNS162. – SEPTEMBER 2011 5.9 Inter-Integrated Circuit (I2C) The inter-integrated circuit (I2C) module is a multi-master communication module providing an interface between the TMS570 microcontroller and devices compliant with Philips Semiconductor I2C-bus specification version 2.1 and connected by an I2C-bus. This module will support any slave or master I2C compatible device. 5.9.1 Features The I2C has the following features: • Compliance to the Philips I2C bus specification, v2.1 (The I2C Specification, Philips document number 9398 393 40011) – Bit/Byte format transfer – 7-bit and 10-bit device addressing modes – General call – START byte – Multi-master transmitter/ slave receiver mode – Multi-master receiver/ slave transmitter mode – Combined master transmit/receive and receive/transmit mode – Transfer rates of 10 kbps up to 400 kbps (Phillips fast-mode rate) • Free data format • Two DMA events (transmit and receive) • DMA event enable/disable capability • Seven interrupts that can be used by the CPU • Module enable/disable capability • The SDA and SCL are optionally configurable as general purpose I/O • Slew rate control of the outputs • Open drain control of the outputs • Programmable pullup/pulldown capability on the inputs • Supports Ignore NACK mode NOTE This I2C module does not support: • High-speed (HS) mode • C-bus compatibility mode • The combined format in 10-bit address mode (the I2C sends the slave address second byte every time it sends the slave address first byte) Copyright © 2011, Texas Instruments Incorporated Peripheral Information and Electrical Specifications 137 Submit Documentation Feedback focus.ti.com: TMS570LS3137 |
