3 S1D13705 Host Bus Interface
3.1 Host Bus Pin Connection
Interfacing to the Philips MIPS PR31500/PR31700 Processor
Issue Date: 01/02/13
This section is a summary of the host bus interface modes available on the S1D13705 that
would be used to interface to the PR31500/PR31700.
The S1D13705 implements a 16-bit interface to the host microprocessor which may operate
in one of several modes compatible with most of the popular embedded microprocessor
families. The interface modes used for the PR31500/PR31700 are:
• Generic #1 (Chip Select, plus individual Read Enable/Write Enable for each byte).
• Generic #2 (External Chip Select, shared Read/Write Enable for high byte, individual
The following table shows the functions of each host bus interface signal.

document number X27A-A-001-xx.
Read/Write Enable for low byte).
