Controller (hereinafter “UDC2”) and AHB. UDC2AB has the DMA controller that supports
the AHB master transfer and controls transfer between the specified address on AHB and the
Endpoint-FIFO (Endpoint I/F) inside UDC2.

connected. However, the DMA controller in UDC2AB (AHB master function) can be
connected with only one Rx-EP and one Tx-EP. Accesses to other endpoints (including
EP0) should be made through PVCI I/F of UDC2 using the AHB slave function. Please
note the EPx_FIFO register of a UDC2 endpoint in master transfer with the DMA
controller cannot be accessed through PVCI I/F.
