ARM and SHARC sharing the same TWI

Hello,

is it possible to share TWI with ARM and SHARC (at the same time)? ADSP SC589 dev kit has ADC and DAC, both connected to the same TWI. If I want to use ADC by SHARC, according to this Q/A I have to disable whole TWI node in DTS (disabling only ADC does not work). What if I need to use TWI by both, ARM and SHARC, for example ADC on SHARC and DAC on ARM (just example). TWI is multimaster-slave, so theoretically it should work. Is there any way how can I do this?

 

Thank you!
