I have change the setting of the FCCU, to test the sequence of the EOUT[0] and EOUT[1]. Bellow is the setting .

When the FOM of the FCCU_CFG regisger is set to 0b010 (Bistable) . The output is not change when FCCU go to error state. The sequence of the EOUT[0] and EOUT[1] is not right. EOUT[0] is always high, and EOUT[1] is always low.

They do  not change when the FCCU state changes.

But when the FOM of the FCCU_CFG register is set to 0b000(Dual-Rail) or 0b001(Time-Switching). The output sequence of the EOUT[0] and EOUT[1]  is right.

Could you give me some advices about the setting of the FCCU ? Is there a mistake in the configuration?

regards,

meng
