Data Flow
[FAX Tx]
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.
CPU compress the data in IC400.
CPU transfer the data to MODEM and output it to TEL LINE
through DAA circuit.
