Title

NS9750 Chip Select CS4 and CS5 Initialization Problems

Case: 15810

Date Fixed: 06/24/05

Description

The initialization sequence for CS4 and CS5 (in the NS9750 platform) is backwards, such that the base address is set prior to the mask. This could cause the processor to re-map this chip select inadvertently, potentially overlapping the chip select used to fetch instructions, potentially causing a system to crash when these chip selects are populated.

Solution

The mask register will be set first, followed by the base register.
