All data IN transactions use the Transmit buffers (TX), which are handled by the
DDBGMODIN bits. All data OUT transactions go via the Receive buffers (RX), which
are handled by the DDBGMODOUT bits. Transactions on Control endpoint 0 (IN,
OUT and SETUP) are handled by the CDBGMOD bits.
Interrupts caused by events on the USB bus (SOF, Pseudo SOF, suspend, resume,
bus reset, Setup and High-Speed Status) can also be controlled individually. A bus
reset disables all enabled interrupts except bit IEBRST (bus reset), which remains
unchanged.
The Interrupt Enable Register consists of 4 bytes. The bit allocation is given in
