Function
Setup interrupt enable
Bit SUIE enables the generation of a device interrupt on a succesful reception of
a setup packet which must be processed by the CPU.
If SUIE=0, the setup interrupt is disabled.
If SUIE=1, the setup interrupt is enabled.
Start of frame interrupt enable
bit SOFIE enables the generation of a device interrupt on the detection of a start
