USB 2.0 Full-Speed 8-Bit Micro-Controller  
9.5.11 USB ENDPOINT 4 ENABLE REGISTER  
The communication with the USB host using endpoint 4, endpoint 4’s FIFO is implemented as Z bytes of dedicated  
RAM. The endpoint 4 is an interrupt and bulk endpoint.

UE4E: USB endpoint 4 function enable bit.  
0 = disable USB endpoint 4 function.  
1 = enable USB endpoint 4 function.  
Bit [6:5] UE4M [1:0]: The endpoint 4 modes determine how the SIE responds to USB traffic that the host sends to  
the endpoint 4. For example, if the endpoint 4’s mode bit is set to 00 that is NAK IN/OUT mode as shown in  
Table, The USB SIE will send NAK handshakes in response to any IN/OUT token set to the endpoint 4. The  
bit 5 UE4M0 will auto reset to zero when the ACK transaction complete.
