what happens to the pins of the spi master port on an ADAU1452 when I set the device in reset? Are they going to high-z? In my target application I would like to program the eeprom by a microcontroller which becomes the master on the spi bus during programming. Thus, my idea is to keep the DSP in reset during programming the eeprom.
Can I do it this way or am I running into a conflict with the master spi port of the DSP when the mcu takes over the spi bus?
I know that I could program through the slave port but that did never work for the last three boards although used the same circuit and devices like on the evaluation boards. Therefore, I do not trust in this solution.
