Register 0xD – FPGA Global Reset.
By sending this control word, the FPGA gets reset. Every single register in the FPGA
is reset. The FPGA transmit that command to the:
- DAC, which will need to be reconfigured,
- Clock synthesizers, which keep the internal register values but does not output
any signal,
- Clock multiplexers, which take there default state (external clocks routed to
FPGA, DAC and ADCs)
- The interface implemented in the FPGA, including ComPort interface. It is note
recommended to proceed to an FPGA global reset while communications are
happening. It might stick the other end into an unknown state.
