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.

Processors for
I/OBus Networks

With I/OBus, an I/O Map table is used to define the number, location and type of
I/O devices on the network bus.

All Other
Processors

Other Processor Adapters only use the I/O Map for local I/O. The default of 144
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.
