DESCRIPTIONS
-
The Function Enable outputs two function enable signals to
external stimulus circuit.
At this stage, only the bit 22 is used for external random collision
generator. The random collision generator used only in FPGA
emulation.
-
The Flag Out provides two output flags to trigger Logic Analyzer for
debug. These two bits can be written at any time.
The Configuration controls which group of internal signals can be
multiplexed out for debug. Each group includes 16 signals.
