Data Flow
[FAX Tx]
1. An analog image data is output from CIS unit to IC503.
IC503 decodes the analog data to digital data, and outputs to IC300.
Scanner I/F in IC300 process image data and stores it in IC400
through SDRAM I/F.
2. CPU compresses the data in IC400.
3. CPU transfer the data to MODEM
and outputs it to TEL LINE through DAA circuit.

[FAX Rx]
1. FAX data is input from TEL LINE to MODEM in IC300
through DAA circuit.
And then stored it in IC400 through SDRAM I/F.
2. CPU decompresses the data in IC400.
3. Print I/F retrieves the data from IC400 and outputs it to LSU.
