SN8F2280 Series  
USB 2.0 Full-Speed 8-Bit Micro-Controller  
9.5.7 USB ENDPOINT 0 ENABLE REGISTER  
An endpoint 0 (EP0) is used to initialize and control the USB device. EP0 is bi-directional (Control pipe), as the device,  
can both receive and transmit data, which provides to access the device configuration information and allows generic  
USB status and control accesses.

Bit [6:5] UE0M [1:0]: The endpoint 0 modes determine how the SIE responds to USB traffic that the host sends to  
the endpoint 0. For example, if the endpoint 0’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 0.The  
bit 5 UE0M0 will auto reset to zero when the ACK transaction complete.

Bit [3:0] UE0C [3:0]: Indicate the number of data bytes in a transaction: For IN transactions, firmware loads the  
count with the number of bytes to be transmitted to the host from the endpoint 0 FIFO.  
9.5.8 USB ENDPOINT 1 ENABLE REGISTER  
The communication with the USB host using endpoint 1, endpoint 1’s FIFO is implemented as W bytes of dedicated  
RAM. The endponit1 is an interrupt endpoint.
