Setup Interrupt
SUI is automatically set after a successful reception of a setup packet which
is not handled by the USB module and must be forwarded to the CPU. The
setup packet itself is limited to 8 bytes and stored at USB memory addresses
00H to 07H.
If a setup interrupt occurs, the control and status bits UBF0, CBF0, SOD0
and DIR0 in the endpoint registers EPBS0 and EPIR0 are cleared. DIR0=0
predicts the direction of the next USB access (data phase) to be from host
to CPU.
If a read access is indicated in the SETUP packet, the CPU has to set bit
SETRDn (set read), before data can be written to the corresponding buffer.
Start of Frame Interrupt
SOF is automatically set after detection of a start of frame packet on the
USB.
