DAI Signal Routing Unit Registers
A-132 ADSP-214xx SHARC Processor Hardware Reference
Pin Signal Assignment Registers
(SRU_PINx, Group D)
Each physical pin (connected to a bonded pad) may be routed using the
pin signal assignment registers (see Figure A-70 through Figure A-74) in
the SRU to any of the inputs or outputs of the DAI peripherals, based on
the 7-bit values listed in Table A-78. The SRU also may be used to route
signals that control the pins in other ways.
