Introduction
The MicroSmart provides analog I/O control capabilities of 12- through 16-bit resolution using analog I/O modules.
This chapter describes the system setup for using analog I/O modules, WindLDR programming procedures, data register
allocation numbers for analog I/O modules, and application examples.
For specifications of analog I/O modules, see page 2-43.
Applicable CPU Modules
END refresh type analog I/O modules as many as listed below can be used with any FC4A MicroSmart CPU module sys-
tem program versions.
