[PC Scan]

1. An analog image data is output from CISunit to IC503.

IC503 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F. 

2. If necessary, the data is compressed via DSP. 
3. When you use the LAN, the data is output to PC 

through the LAN I/F and PHY(IC750). 
or
When you use the USB, the data is output to PC 
through the USB I/F.

1.The print data is output from PC through LAN

and pass the PHY(IC750) and LAN I/F in IC300. 
or
The print data is output from PC through USB
and pass the USB I/F in IC300.
then the data is stored in IC400 through SDRAM I/F.

2. Print I/F retrieve the data from IC400 and output it to LSU.
