ADSP-2185L  
Memory Interface Pins  
Common-Mode Pin Descriptions  
The ADSP-2185L processor can be used in one of two modes,  
Full Memory Mode, which allows BDMA operation with full  
external overlay memory and I/O capability, or Host Mode,  
which allows IDMA operation with limited external addressing  
capabilities. The operating mode is determined by the state of  
the Mode C pin during RESET and cannot be changed while  
the processor is running. See tables for Full Memory Mode Pins  
and Host Mode Pins for descriptions.
