'''Function:''' USB Events Mask

This port is a mask for what errors [[83Plus:Ports:86|port 86]] will report.

Set the corresponding bits here to receive notifications via port 86.

=== Values ===
* Bit 0: Possibly set if the bus has been suspended (no activity for some length of time.)
* Bit 1: Unknown; probably related to HNP and/or SRP.
* Bit 2: Set if a bus reset has occurred (both D+ and D? pulled low for some length of time.)
* Bit 3: Unknown.
* Bit 4: Possibly set if a device has been connected (D+, or maybe D?, pulled high for some length of time.)
* Bit 5: This usually indicates that something was unplugged.
* Bit 6: Unknown; probably related to HNP.
* Bit 7: Calculator cannot provide sufficient power. Usually caused by low batteries, although, some devices cause this every time.
