Message Registers allow data to be sent to the other side, but not to be read back by the side that wrote the data. This allows smaller FPGA implementations by duplicating the storage and removing muxes in the design. It is incompatible with old debuggers, if they use these registers in surprising ways.

Bits is more general, assuming less about the implementation.

Message Registers allow data to be sent to the other side, but not to be
read back by the side that wrote the data.
This allows smaller FPGA implementations by duplicating the storage and
removing muxes in the design, addressing part of #717.
