GR712RC
The SpaceWire transmitter uses SDR output registers meaning that the bitrate will be equal to the
transmit clock. The SpaceWire input signals are sampled synchronously with DDR registers using the
transmit clock. This allows the GR712RC to receive SpaceWire data at a bitrate equal to the transmit
clock.
16.9 Registers
The core is programmed through registers mapped into APB address space.The table below shows the
base address and interrupt number for each GRSWP core.
