About "external delay" in ADAU1452,how to use the module(SPI RAM delay )?
How about Setting the Master Control port Properties？
The "external SPI RAM delay" block for the ADAU1452 was developed/tested for the Microchip 23K256 SPI RAM. (see: http://ww1.microchip.com/downloads/en/DeviceDoc/22100D.pdf)
The SPI Master Port is limited 20 MHz and is limited to a 24bit address max, so approximately 16MByte.
The Master Control Port is used on system startup to communicate with 1 slave device (only), either a SPI flash or slave SPI device (like a codec). The Sequencer File is a text file which contains the SPI data words to be written to the device.
Unfortunately there is not any documentation on these blocks on the Wiki. We are looking to add that information in the coming weeks.
Really thanks for your reply.
Use SPI RAM will need Master Control Port? How to set up?
SPI RAM model we are using Microchip 23LC1024.
And my SPI RAM hardware schematics as follows:
