Bus Interface and Access to FIFO
(1) CPU bus interface
packet mode, FIFO capacity that is implemented by hardware is used as large FIFO.
In dual packet mode, FIFO capacity is divided into two and used as two FIFOs. It is
also used as an independent FIFO. Even if the UDC is transmitting and receiving to
USB host, it can be used as an efficient bus by possible load to FIFO.
“0”, FIFO register runs in single mode.
Sample: Where endpoint 1 is used to dual packet of payload 64 bytes.
The UDC prepares two types of FIFO access, single packet and dual packet. In single
But control transfer type receives only single packet mode.
Epx_SINGLE signal in dual packet mode must be fixed to “0”. If this signal is fixed to
