13.14.1 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 13-26: 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
.
