Notes
17. These interrupts are to be set to 1 when “ENCOMPARATOR” bit 7 in the 07h register set to “1” AND no valid VBUS supply is at preset. If
“ENCOMPARATOR” bit 7 is reset to “0” in no valid VBUS supply, these interrupt events are in no response.
18. These interrupts are to be forcibly overridden to alert the interrupt events in a valid VBUS attached.
