Controller
1) Serial Interface Engine (SIE)
SIE implements NRZI decoding/encoding, CRC generation and checking. It also provides an interface signal
for the external USB transceiver.
2) Serial Interface Unit (SIU)
It implements an endpoint address decoding for the USB packet.
3) Endpoint Controls
Endpoint 0 controller only implements a control transfer. Other endpoints (1-3) can set up In/Out randomly
using the setting of the In/Out programming bit. However, once the direction is set up, it cannot be changed.
Also, aach endpoint can be set up as isochronous, bulk or interrupt type.
