29.2.1 Step Commands and Format

The PTG operates using eleven 8-bit step commands to perform higher level tasks. There are four types of step commands:
  • Input Event Control
  • Control Functions
  • Flow Control
  • Output Generation

Combinations and sequences of these commands can be used to make decisions and take action without CPU intervention.
