Incrementing address	Incrementing address only

The RMAP read incrementing address command is supported in the SpaceWire router. The read incrementing address is used to read a continuous block of registers from the SpaceWire router, e.g. the complete group adaptive routing table can be read in one command or all the status registers for the SpaceWire links can be read in one command.
