I am working on ADSP-21469 processor. I would like to know a way to set DPI pins to High-Z state without resetting the processor.
Initially I will be using as output but based on the requirement need to change back and forth to High-Z state
I understand this can be done by DPI_PBEN13_I but not sure how. Is there any SRU macro that disconnect the enable signal from pin buffer circuitry?
Initialization of the PIN as OUTPUT
sysreg_bit_set( sysreg_FLAGS, FLG7O );
set and clear
Appreciate your help in this regard.
