Destination		The destination key identifier must match the contents of the destination key				1
Key		register, see section 9.5.10.

Source		The source path address field is used to add source path addresses to the				0,4,8,12
Path		head of the reply packet. The expected number of source path addresses is
Address		specified in the command byte. See section 7.6.9 for source path address
		decoding.

Source		The source logical address should be set to the logical address of the node				1
Logical		which sent the command or it should be set to the default value of FEh.
Address

Transaction		The transaction identifier identifies the command packet and reply packet				2
Identifier		with a unique number.

Extended		The extended read address is not used in the SpaceWire router and shall				1
Read		always be set to zero.
Address

Read		The read address identifies the start address for the read incrementing				4
Address		command. The valid starting read addresses are defined in section 9.

Data		The data length defines the number of bytes to read from the router. Valid				3
Length		data lengths are in the range 4-1064. 1064 allows the all the router registers
		to be read in one command. If the data length field is not a multiple of four
		bytes then the command is rejected by the SpaceWire router.

Header		The header CRC is the eight bit CRC code used to detect errors in the				1
CRC		command packet. The CRC code is checked before the command is
		executed.
