Command Column Design Constraints
- limitation = 20 characters length column length
Possibilities
- 1- auxiliary digit I/O outputs 1's | 0's ... quantity=7 - triggered at the beginning of the design profile segment
- 2- a file name -
- 3- command strings - make an extensible interface. Allow messages to be sent in & out.
Controller Driver Notes - Writing output state
- MAXDIGOUT - is a constant = 35 so I assume the unused are available for digital I/O
- The address of the digital I/O registers
Controller Driver Notes - Reading output state
- in order to use more than one output you must read and mask off the output bit register to prevent changing other bits
