Memory Interface Pins
The ADSP-2186M processor can be used in one of two modes: Full Memory Mode, which allows BDMA operation with full exter-
nal 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.
The following tables list the active signals at specific pins of the DSP during either of the two operating modes (Full Memory or
Host). A signal in one table shares a pin with a signal from the other table, with the active signal determined by the mode set. For the
shared pins and their alternate signals (e.g., A4/IAD3), refer to the package pinout tables.
