Master Control Port (ADAU145X)

The Master Control Port library in the ToolBox lists blocks that utilize the ADAU145x processor family's master control port. These devices contain a combined I2C and SPI bus port accessible from a DSP program.

The master control port can be used for several purposes, as follows:

• Self boot the ADAU145x processor from an external serial EEPROM.
• Boot and control external slave devices such as codecs and amplifiers.
• Read from and write to an external SPI RAM or flash memory.
• Monitoring external I2C slaves during runtime
• Reading a wav file from SPI flash and playing
• Monitoring external SPI slaves during runtime

The following blocks are available:

• Flash Programmer
• I2C Read
• Master Control Port Boot Time I/O (Single Slave)
• Master Control Port Boot Time I/O (Multiple Slaves)
• Master Control Port Runtime Sequential Write (Multiple Slaves)
• Master Control Port Status
• Real Time Variant
• SPI Read
• Wav Player
