Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7–4 | OSS4-OSS1 | R/W | 0 | Port power priority bits, one bit per port, if 1-bit shutdown priority has been selected. It is used to determine which port is shut down in response to an external assertion of the OSS fast shutdown signal. The turn off procedure (including register bits clearing) is similar to a port reset using Reset command (1Ah register), except that it does not cancel any ongoing fault cool down time count. 1 = When the OSS signal is asserted, the corresponding port is powered off. 0 = OSS signal has no impact on the port. |
3–0 | DCUT4-DCUT1 | R/W | 0 | ICUT disable for each port. Used to prevent removal of the associated port’s power due to an ICUT fault, regardless of the programming status of the Timing Configuration register. Note that there is still monitoring of ILIM faults. 1: Port’s ICUT is disabled. This means that an ICUT fault alone will not turn off this port. 0: Port’s ICUT is enabled. This enables port turn off if there is ICUT fault. Note that if ICUT is disabled for a port, this port will not be automatically turned off during an ICUT fault condition. However, the ICUT fault flag will still be operational, with a fault timeout equal to tLIM/2. |
