Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7–4 | — | R/W | 0 | |
3–0 | DCDE4–DCDE1 | R/W | 0 | DC disconnect enable. DC disconnect consists in measuring the port DC current at SENn, starting a timer (TDIS) if this current is below a threshold and turning the port off if a time-out occurs. Also, the corresponding disconnect bit (DISFn) in the FAULT EVENT register is set accordingly. The TDIS counter is reset each time the current goes continuously higher than the disconnect threshold for nominally 15 msec. The counter does not decrement below zero. Look at the TIMING CONFIGURATION register for more details on how to define the TDIS time period. |
