11.10.7.12 USB End of Transfer Interrupt Set register (USBEoTIntSet - 0x5000 C2A8)
Writing one to a bit in this register sets the corresponding bit in the USBEoTIntSt register.
Writing zero has no effect. USBEoTIntSet is a write-only register.
11.10.7.13 USB New DD Request Interrupt Status register (USBNDDRIntSt - 0x5000
C2AC)
A bit in this register is set when a transfer is requested from the USB device and no valid
DD is detected for the corresponding endpoint. USBNDDRIntSt is a read-only register.
11.10.7.14 USB New DD Request Interrupt Clear register (USBNDDRIntClr - 0x5000
C2B0)
Writing one to a bit in this register clears the corresponding bit in the USBNDDRIntSt
register. Writing zero has no effect. USBNDDRIntClr is a write-only register.
11.10.7.15 USB New DD Request Interrupt Set register (USBNDDRIntSet - 0x5000
C2B4)
Writing one to a bit in this register sets the corresponding bit in the USBNDDRIntSt
register. Writing zero has no effect. USBNDDRIntSet is a write-only register
