Configuring an M1 CPU with Concept

Changing the Size of the I/O Map

Introduction

The default size of the I/O Map is 144 words. You may want to adjust this number to

 

 

provide more support for an I/OBus network or to increase the size of the full logic

 

 

area.

With I/OBus, an I/O Map table is used to define the number, location and type of

words is more than sufficient for any Momentum I/O base. Depending on the

 

 

requirements of your I/O base, you may be able to reduce the number of words to

 

 

the minimum, 4, in order to increase the Available Logic Area.
