8.2 USBMSK: USB Interrupt Mask Register (XDATA at F007)
Bits[5:0] of the USBMSK register provide a mechanism to allow the MCU and firmware to enable or disable
the generation of certain types of interrupts based on the corresponding status or events that occurred.
The USBMSK register is cleared by a power up or a WDT reset. A USB reset cannot reset the USBMSK
register.
