SpaceWire port will wait until the 
other end of the link tries to 
make a connection and will then 
automatically start. 

13 

Start 

‘0’ 

When set then the SpaceWire 
link will initiate start-up as 
defined in the SpaceWire 
standard [AD1]: the SpaceWire 
port will try to make a connection 
with the other end of the link. 

R/W 

14 

Disable 

‘0’ 

When set then the SpaceWire 
link will be disabled as defined in 
the SpaceWire standard [AD1]: 
the SpaceWire port will not start 
and will not respond to any 
attempt to make a connection by 
the other end of the link. 

R/W 

15 

Deactivate 

‘0’ 

When set the DOUT and SOUT 
serial SpaceWire signals will be 
deactivated dependent on the 
state of the SpaceWire link 
interface.  The DOUT and SOUT 
deactivate output state 
mappings are listed below:

Note:  DOUT is deactivated one 
system clock cycle before SOUT

due to output port deactivation 
do not occur.

22:16 Transmitter 

data signalling 
rate 
(TXRATE) 

Bits 18 to 16 are set 
according to the 
POR_TX_RATE(2:0) pins. 
Bits 22:18 are set to zero. 

Allows the SpaceWire link data 
signalling rate to be set. 

See section 8.1.6 for details on 
how to set the TXRATE bits. 

Note: bits 22:16 must not be set 
to all ones. Bits 22:16 must not 
be set to give a transmit rate of 
less than 2 Mbits/s.
