| BITS | D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
|---|---|---|---|---|---|---|---|---|
| BIT NAME | ILIM4 | ILIM3 | ILIM2 | ILIM1 | STRT4 | STRT3 | STRT2 | STRT1 |
| RESET or POR VALUE | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Active high, each bit corresponds to a particular event that occurred.
Each bit ILIMn, STRTn represents an individual port.
A read at each location (08h or 09h) returns the same register data with the exception that the Clear-on-Read command clears all bits of the register. These bits are cleared by I2C power-off command (POFFn) or port-reset command (RESPn).
If this register is causing the INT pin to be activated, this Clear-on-Read command releases the INT pin.
Any active bit has an impact on the Interrupt Register as indicated in the Interrupt Register description.
Bit Descriptions
STRT4-STRT1: Indicates that a start fault occurred at port turn on. This may be caused by:
1 = Inrush fault or class/detect error occurred.
0 = No inrush fault or class/detect error occurred.
ILIM4-ILIM1: Indicates that an ILIM fault occurred, which means the port has limited its output current to ILIM or the folded back ILIM for more than tLIM.
1 = ILIM fault occurred.
0 = No ILIM fault occurred.
