XPS IIC Bus Interface (v2.03a)
DS606 June 22, 2011
Product Specification
Introduction
This product specification defines the architecture,
hardware (signal) interface, software (register) interface
and parameterization options for the XPS IIC module.
It provides a low speed, two wire, serial bus interface to
a large number of popular devices. XPS IIC supports all
features, except high speed mode, of the Philips I²C
bus, V2.1, Release January 2000. (See the Specification
Exceptions section for more details.)
Features
• Connects as a 32-bit Slave on PLB V4.6 bus of 32, 64
and 128 bits data width
• Master or slave operation
• Multi-master operation
• Software selectable acknowledge bit
• Arbitration lost interrupt with automatic mode
switching from master to slave
• Calling address identification interrupt with
automatic mode switching from master to slave
• START and STOP signal generation/detection
• Repeated START signal generation
• Acknowledge bit generation/detection
• Bus busy detection
• Fast mode 400 KHz operation or standard mode 100
KHz
• 7 bit or 10 bit addressing
• General call enable or disable
• Transmit and receive FIFOs - 16 bytes deep
• Throttling
• General purpose output, 1 bit to 8 bits wide
• Dynamic Start/Stop generation
• Filtering on the SCL and SDA signals to eliminate
spurious pulses
