13.18.1 SpaceWire basics
The SpaceWire links are a Point-to-point (P2P) connection between a node and
another node or a rooter. The link is full-duplex bidirectional serial data link.
The SpaceWire has two types of characters:
●
Data characters containing a parity bit, a data control flag and eight bits of data.
Figure 13-108: SpaceWire data characters
●
Control characters containing a parity-bit, a data-control flag and the 2-bit control
code. The data control flag is set to 1 and indicates that this is a control character.
Figure 13-109: SpaceWire control characters
Also there are two control codes:
●
NULL code consisting of an Escape (ESC) and a Flow Control Token (FCT)
