MEMORY INTERFACE PINS
ADSP-218xN series members 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
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 sig-
nal from the other table, with the active signal determined by
the mode that is set. For the shared pins and their alternate sig-
nals (e.g., A4/IAD3), refer to the package pinouts in Table 27 on
TERMINATING UNUSED PINS
Table 12 shows the recommendations for terminating unused
pins.

For Emulation Use
1 Interrupt/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.
2 SPORT configuration determined by the DSP System Control Register. Software configurable.
