Data Flow
[FAX Tx]
1. An analog image data is output from CIS unit 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. CPU compress the data in IC400. 
3. CPU transfer the data to MODEM 
    and output it to TEL LINE through DAA circuit.
