Use the following steps to initialize the CN8223 for proper UTOPIA port operation:
1.
Put RS8234 in the global reset: write 0x40000000 to CONFIG0.
2.
Write RS8234
s CONFIG0 to appropriate values, but do not overwrite the
GLOBAL_RESET bit.
3.
Put CN8223 in the reset mode: write 0x0080 to CONFIG_5.
4.
Initialize CN8223, including UTOPIA interface if needed.
5.
Release CN8223 reset: write 0x0000 to CONFIG_5.
6.
Release RS8234 reset: set GLOBAL_RESET bit to 0.
7.
Enable RS8234
s Reassembly coprocessor.
8.
Enable CN8223
s Receiver: write 0x0C02 to CELL_VAL register.
9.
Enable RS8234
s Segmentation coprocessor.
