9.8.11 USB End of Transfer Interrupt Clear register (USBEoTIntClr - 0xFFE0 C2A4)
Writing one to a bit in this register clears the corresponding bit in the USBEoTIntSt
register. Writing zero has no effect. USBEoTIntClr is a write only register.
9.8.12 USB End of Transfer Interrupt Set register (USBEoTIntSet - 0xFFE0 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.
9.8.13 USB New DD Request Interrupt Status register (USBNDDRIntSt - 0xFFE0
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.

0xFFE0 C2AC) bit description
Bit Symbol Value Description Reset value
31:0 EPxx Endpoint xx (2 ≤ xx ≤ 31) new DD interrupt request. 0
0 There is no new DD interrupt request for endpoint xx.
1 There is a new DD interrupt request for endpoint xx.
