XMOS
A LLinkcan be paused by transmitting one of the PAUSE tokens, followed by a
NOP token that brings all five wires to a low state.
NOTE: The physical layer transmits tokens 0x1 and 0x2 using two escapes; they
are not transmitted using the conventional single escape for control tokens less
than 64. It is also the task of the physical layer to transmit a NOP after either a
PAUSE or END token. Finally, on reception of a double escape END or PAUSE
token, the physical layer must report this as a 0x1 or 0x2 control token, and the
physical layer shall discard any NOP tokens that are received.
The encoding of the four hardware tokens operated by the physical layer is:
The PAUSE and END tokens are application level control tokens, and their en-
codings for higher levels are discussed in Section 3.6.1.
3.1.3 XS1-L Physical layer configuration
Bits are transmitted at a speed that is set under software control. Both speed
and width are set by writing to the Link’s speed register. Each of the speed reg-
isters specifies the width of the link, the gap between bits, and the gap between

2. Set wire “4” to high (signals a second escape, this is an END).
3. Set wire “0” to low.
4. Set wire “1” to low. Sends the END token, and only wires “4” and “2” are
5. Set wire “4” to low (signals an escape).
6. Set wire “3” to high (transmits token value 11).
7. Set wire “3” to low (transmits token value 11).
8. Set wire “2” to low (transmits token value 10). This has transmitted token
left high; hence, a NOPE token must be transmitted.

now low.
