Finite State Machine Register 1 (FSM1)
The FSM1 shows the current value of the FSM (Finite State Machine) of the function module in EMC.
The FSM1 is read only and write to it has no effect. The FSM1 is used only for debug.

Debug Configuration Register (DCR)
The DCR is for debug only to multiplex different signal group out. In FPGA emulation, the signals are
outputted to probe pins in emulation board. In real chip, the signals are outputted through the GPIO
pins.
