Block Diagram
This USB controller contains 3 sets of FIFO. The
ENDP0 FIFO
is an 8-byte FIFO to store/transmit the
endp0 control packet. The
FIFO0
and
FIFO1
are a set of 64-byte ping-pong FIFO for endp1 and endp2. FIFO0
is used for DATA0 packet and FIFO1 is for DATA1 packet. When they are served as the endp1 FIFO, the
LINKFF bit of FFCFG should be set and LINKDIR bit of FFCFG should be cleared. It they are allocated as the
endp1 FIFO, then LINKDIR should be set.
An EPP engine is included to automatically accessing data to/from external device ASIC. Firmware can set
the data length and hardware will count down to decide the last byte.
There are two sets of registers :
I/O register
and
USB register
. The
USB register
is controlled by
micro-controller to implement the USB endpoint 0 functions. The
is the main register to interface the
data accessing between this controller and external device.
