3 S1D13706 Host Bus Interface
3.1 Host Bus Interface Pin Mapping
Interfacing to the Motorola MCF5307 "ColdFire" Microprocessor
Issue Date: 01/02/23
The S1D13706 directly supports multiple processors. The S1D13706 implements a 16-bit
Generic #1 Host Bus Interface which is most suitable for direct connection to the Motorola
MFC5307 microprocessor. Generic #1 supports a Chip Select and an individual Read
Enable/Write Enable for each byte.
The Generic #1 Host Bus Interface is selected by the S1D13706 on the rising edge of
RESET#. After RESET# is released, the bus interface signals assume their selected config-
uration. For details on the S1D13706 configuration, see Section 4.2, "S1D13706 Hardware
Configuration" on page 14.
The following table shows the functions of each Host Bus Interface signal.
