Overview
The I/O Module is a light-weight implementation of a set of standard I/O functions
commonly used in a MicroBlaze™ processor sub-system. The input/output signals of the I/O
Module are shown in
Table 2-3. See the description of LMB Signals in the MicroBlaze Bus Interfaces chapter in the
MicroBlaze Processor Reference Guide
.
