The USB module handles all transactions between the universal serial bus USB and the
internal (parallel) X-Bus of the CPU. The USB module includes several units which are
required to support data handling with the USB bus:
• An onchip USB bus transceiver
• An USB memory with 2 pages of 256 bytes each
• The memory management unit (MMU) for USB module and µC memory access
• The USB device core (UDC) for USB protocol handling
• A XBUS interface with the USB specific special function registers and an PD-Bus
Figure 22-1 shows the block diagram of the functional units of the USB module with their
interfaces.
