		Table 9-5 Configuration Port Control/Status Register Fields

Bits		Name	Reset	Description			Read/Write
			Value

0		Error active	‘0’	The error active bit is set when one of the error			R
				bits is active

1		Port timeout error	‘0’	The port timeout error bit is set when a timeout			R
				event is detected by the configuration port
				routing logic.

2		Invalid Header	‘0’	The Invalid header CRC bit is set when the			R
		CRC		header CRC is invalid.

3		Invalid Data CRC	‘0’	The invalid data CRC is set when the data part			R
				of the packet is corrupted and the CRC does
				not match the internally generated CRC.

4		Invalid Destination	‘0’	The invalid destination key bit is set when the			R
		Key		destination key in the command packet is
				invalid.

5		Command not	‘0’	The command not implemented bit is set when			R
		implemented		the command code is a valid RMAP code but
				the command is not supported by the
				SpaceWire Router.

6		Invalid Data Length	‘0’	The invalid data length bit is set when a data			R
				length error is detected

7		Invalid RMW Data	‘0’	The read modify write command data length is			R
		Length		invalid. When a read modify write is performed
				the expected data length is 8.

8		Invalid Destination	‘0’	The invalid destination logical address bit is set			R
		Logical Address		when the destination logical address in the
				command packet is not the default value of
				254.

9		Early EOP	‘0’	The early EOP bit is set when the command			R
				packet is terminated before the end of packet
				with an EOP

10		Late EOP	‘0’	The late EOP bit is set when the command			R
				packet is not terminated correctly and trailing
				bytes are detected before the end of packet.

11		Early EEP	‘0’	The early EEP bit is set when the command			R
				packet is terminated before the end of packet
				with an EEP

12		Late EEP	‘0’	The late EEP bit is set when the command			R
				packet is not terminated correctly and trailing
				bytes are detected before the end of packet.

13		Verify Buffer	‘0’	The verify buffer overrun error bit is set when a			R
		Overrun Error		verified write command is performed and the
				data length is not 4.
