Command Column Design Constraints[edit]

  • limitation = 20 characters length column length

Possibilities[edit]

  • 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[edit]

  • in order to use more than one output you must read and mask off the output bit register to prevent changing other bits

  • MAXDIGOUT - is a constant = 35 so I assume the unused are available for digital I/O



  • The address of the digital I/O registers
