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
LSBD
and
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
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.
