3 S1D13706 Host Bus Interface
3.1 Host Bus Interface Pin Mapping
Interfacing to the Intel StrongARM SA-1110 Microprocessor
Issue Date: 02/06/26
The S1D13706 directly supports multiple processors. The S1D13706 implements a 16-bit
Generic #2 Host Bus Interface which is most suitable for direct connection to the
SA-1110.
The Generic #2 Host Bus Interface is selected by the S1D13706 on the rising edge of
RESET#. After releasing reset the bus interface signals assume their selected configuration.
For details on S1D13706 configuration, see Section 4.2, "S1D13706 Hardware Configu-
ration" on page 14.
The following table shows the functions of each Host Bus Interface signal.
