PRODUCTION DATA.
COMMAND = 10h with 1 Data Byte, Read only
Each bit represents the actual power status of a port.
Each bit xx1-4 represents an individual port..
These bits are cleared when port n is turned off, including if the turn off is caused by a fault condition.
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
PG4 | PG3 | PG2 | PG1 | PE4 | PE3 | PE2 | PE1 |
R-0 | R-0 | R-0 | R-0 | R-0 | R-0 | R-0 | R-0 |
LEGEND: R/W = Read/Write; R = Read only; -n = value after reset |
Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7–4 | PG4–PG1 | R | 0 | Each bit, when at 1, indicates that the port is on and that the voltage at DRAINn pin has gone below the power good threshold during the port turn on. These bits are latched high once the turn on is complete and can only be cleared when the port is turned off or at RESET/POR. 1 = Power is good 0 = Power is not good |
3–0 | PE4–PE1 | R | 0 | Each bit indicates the ON/OFF state of the corresponding port. 1 = Port is on 0 = Port is off |
