84 / 114 page  Programmable USB Port Power Controller with Charger Emulation Datasheet Revision 1.4 (07-16-13) 84 SMSC UCS1002 DATASHEET 10.7 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 7.6.1, "Auto-recovery Fault Handling"). Once the Auto-recovery fault handling algorithm has checked the over-temperature and back-drive conditions, 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. Bits 6 - 4 - TCYCLE[2:0] - Defines the delay (tCYCLE) after the Error state is entered before the Auto- recovery fault handling algorithm is started as shown in Table 10.15. Bits 3 - 2 - TRST_SW[1:0] - Sets the tRST time as shown in Table 10.16.
