S1D13706
X31B-G-014-02
The S1D13706 implements a 16-bit native REDCAP2 host bus interface which is used to
interface to the REDCAP2 processor.
The REDCAP2 host bus interface is selected by the S1D13706 on the rising edge of
RESET#. After releasing reset, the bus interface signals assume their selected configu-
ration. For details on S1D13706 configuration, see Section 4.3, "S1D13706 Hardware
Configuration" on page 15.
The following table shows the functions of each Host Bus Interface signal.
