7.1.1.3.2 Delay
  • Behavior
    • Timer counter runs on clock source determined from RC measurement cycle
    • RC = High
    • Q = High
    • Q = Low
  • Transitions
    • In
      • From reset timer counter state, task complete
    • Out
      • To ready state, clear active
      • To RC measurement cycle, trigger
      • To increment cycle counter state, timer counter value ≥ saved timer count value from RC measurement process
