ADSP-218xN Series
–6–
REV. 0
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 running.
Table 3
and
Table 4
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 that is set. For the
shared pins and their alternate signals (e.g., A4/IAD3), refer
to the package pinouts in
Table 27 on page 40
and
Table 28
on page 42
.
