Auto-Recovery Configuration
Register
The contents of this register are retained in Sleep.
The Auto-Recovery Configuration register sets the
parameters used when the auto-recovery Fault
handling algorithm is invoked (see Section 7.5.1
“Auto-Recovery Fault Handling”
).
Once the auto-recovery Fault handling algorithm has
checked the overtemperature and backdrive condi-
tions, it will set the ILIM value to ITEST, and then turn on
the port power switch and start the tRST timer. If, after
the timer has expired, the VBUS voltage is less than
VTEST, then it is assumed that a short-circuit condition
is present and the Error state is reset.
