5.1.2 External Input Source
External shutdown inputs provide the fastest way to safely suspend CWG operation in the event of a Fault condition. When any of the selected shutdown inputs goes active, the CWG outputs will immediately go to the selected override levels without software delay. The override levels are selected by the CWGxB and CWGxD Auto-Shutdown State Control (LSBD) and CWGxA and CWGxC Auto-Shutdown State Control (LSAC) bits. Several input sources can be selected to cause a Shutdown condition. All input sources are active-low. The shutdown input sources are individually enabled by the CWG Auto-Shutdown Source Enable (ASyE) bits.
Important: Shutdown inputs are level sensitive, not edge
sensitive. The Shutdown state cannot be cleared, except by disabling auto-shutdown, as
long as the shutdown input level persists.
