How do I program or configure a PIXI design using the MAX11300?
PIXI I/O ports have multiple modes that the engineer “configures” as different modes of operation. Configuration is the process of loading data (or programming) on the MAX11300 chip. Programming or configuring a PIXI design is quite simple. The Configuration Software is used to select the mode for each port and then the configuration bitstream is created. In reality, this is a series of registers with the register address and data contents given as an output from the Configuration Software tool. At power-on, all PIXI I/O ports are set to high-impedance mode. Configuration downloads a serial data stream to the PIXI registers to set up the mode of operation for each I/O. This bit stream is often stored in a device such as a serial EEPROM, i.e., a 2Kbyte EEPROM can store the PIXI configuration data. After configuration, the PIXI device is ready for normal operation. Since PIXI technology is volatile, anytime a brownout occurs, the device will need to be reconfigured.
