NOTES
1Interrupt/Flag pins retain both functions concurrently. If IMASK is set to
enable the corresponding interrupts, the DSP will vector to the appropriate
interrupt vector address when the pin is asserted, either by external devices or
set as a programmable flag.
2SPORT configuration determined by the DSP System Control Register. Soft-
ware configurable.
Memory Interface Pins
The ADSP-2186 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.
