25.11.2.2 Auto-Restart
When the REN bit is set (REN = 1), the CWG module
will restart from the Shutdown state automatically.
Once all Auto-Shutdown conditions are removed, the hardware will automatically clear SHUTDOWN. Once SHUTDOWN is cleared, the CWG module will resume operation upon the first rising edge of the CWG data input.
Important: The SHUTDOWN bit cannot be cleared in software
if the Auto-Shutdown condition is still present.
