4 REDCAP2 to S1D13706 Interface
4.1 Hardware Description
The interface between the S1D13706 and the REDCAP2 requires no external glue logic.
The information in this section describes the environment necessary to connect the
S5U13706B00C Evaluation Board and the Motorola DSP56654 Application Development
Module (ADM). For a list of connections between the pins and signals of the REDCAP2
and the S1D13706 see Table 4-1:,“List of Connections from REDCAP2 ADM to
S5U13706B00C” on page 13.
The following figure demonstrates a typical implementation of the S1D13706 to
REDCAP2 interface.

System
When connecting the S1D13706 RESET# pin, the system designer should be aware of all
conditions that may reset the S1D13706 (e.g. CPU reset can be asserted during wake-up
from power-down modes, or during debug states).
