Inter-Integrated Circuit (I2C)
The inter-integrated circuit (I2C) module is a multi-master communication module providing an interface
between the RM4x 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.
5.8.1
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)
