Program M3NF is an analog input-handler designed to provide a software interface with the NEFF 620 Analog-to-Digital Converter Subsystem. The handler can be implemented in a MAX III REV I.00 or later operating system. The handler is of the conventional type in which each requested operation is queued by the Basic I/0 System (BIOS). The NEFF 620 Controller is a dual-control section type, i.e., there are separate control sections for input of the digitized, analog data and for output of scan table values. The NEFF 620 Controller Description and the Model 4701 Interval Timer Specification Documents were used as the design criteria for the handler. The handler supports two operating modes of the controller: Register I/0 Mode and DMP (Direct Memory Processor) Mode. In addition, an external convert signal supplied by the Mode 4701 Interval Timer can be used to control the controller convert command. The handler does support NEFF controller operation using the controller internal convert mode. 5 figures, 4 tables.
